Namespaces:

• Valum - Valum is a Web micro-framework written in Vala.

Classes:

• AsteriskRoute - Route supporting the asterisk '*' path.
• Context - Routing context that stores various states for middleware interaction.
• MatcherRoute - Route based on a Valum.MatcherCallback.
• PathRoute - Route based on exact path matching.
• RegexRoute - Route based on GLib.Regex.
• Route - Describe a matching and handling process for a pair of VSGI.Request and VSGI.Response objects.
• Router - Dispatches incoming requests to the appropriate registered handler.
• RuleRoute - Route based on the rule system.

Enums:

• CacheControlDirective
• DecodeFlags
• Method - Represent a set of HTTP methods.

Error domains:

• ClientError - Client errors corresponding to the 4xx HTTP status codes.
• Informational - Informational status corresponding to the 1xx HTTP status codes.
• Redirection - Redirection corresponding to the 3xx HTTP status codes.
• ServerError - Server errors corresponding to the 5xx HTTP status codes.
• Success - Success corresponding to the 2xx HTTP status codes.

Delegates:

• public delegate bool AuthCallback (Authorization auth)
  Perform the authentication against the credentials source.
• public delegate void ContextForeachFunc (string key, Value value, uint depth)
  Type of function passed to Valum.Context.foreach to iterate in all context entries depth-wise.
• public delegate bool ForwardCallback<T> (Request req, Response res, NextCallback next, Context context, T value) throws Error
  Define a type of Valum.HandlerCallback that forward a generic value.
• public delegate bool HandlerCallback (Request req, Response res, NextCallback next, Context context) throws Error
  Handle a pair of request and response.
• public delegate void LoaderCallback (Router router)
  Loads Route instances on a provided router.
• public delegate bool MatcherCallback (Request req, Context context)
  Match the request and populate the Valum.Context.
• public delegate bool NextCallback () throws Informational, Success, Redirection, ClientError, ServerError, Error
  Continuation passed in a Valum.HandlerCallback to *keep routing* both VSGI.Request and VSGI.Response.
• public delegate bool SafeHandlerCallback (Request req, Response res, SafeNextCallback next, Context ctx) throws Informational, Success, Redirection, ClientError, ServerError
  Define a kind of Valum.HandlerCallback which may only raise status codes so that other errors have to be explicitly handled.
• public delegate bool SafeNextCallback () throws Informational, Success, Redirection, ClientError, ServerError

Methods:

• public HandlerCallback authenticate (Authentication auth, owned AuthCallback callback, owned ForwardCallback<string> forward = forward)
  Challenge incoming requests against the provided authentication definition.
• public HandlerCallback basepath (string path, owned HandlerCallback forward)
  Rebase and forward requests which path match the provided basepath.
• public HandlerCallback basic ()
  Provide a set of basic behaviours such as status and error handling.
• public HandlerCallback cache_control (CacheControlDirective directive, TimeSpan max_age = 0)
  Produce a 'Cache-Control' response header.
• public HandlerCallback decode (DecodeFlags flags = NONE)
  Decode any applied 'Content-Encoding'.
• public string[] extract_subdomains (string domain, uint skip = 2)
  Extract subdomains from a domain name excluding the top and second level domain.
• public bool forward (Request req, Response res, NextCallback next) throws Error
  Used as a default value when all that is necessary is to call the 'next' continuation.
• public ForwardCallback<T> forward_with<T> (owned HandlerCallback handle)
  Forward using a provided handler callback.
• public HandlerCallback safely (owned SafeHandlerCallback forward)
  Perform some operations safely.
• public HandlerCallback sequence (owned HandlerCallback a, owned HandlerCallback b)
  Produce a handler sequence of 'a' and 'b'.
• public HandlerCallback status (uint status, owned ForwardCallback<Error> forward)
  Handle any corresponding error thrown by the following handler.
• public HandlerCallback subdomain (string expected_subdomain, owned ForwardCallback<string> forward, bool strict = false, uint skip = 2)
  Produce a matching middleware that accepts request which subdomain is consistent with the expectation.
• ContentNegotiation - Content negociation for various headers.

Methods:

• public HandlerCallback accept (string content_types, owned ForwardCallback<string> forward = forward)
  Negotiate a 'Accept' header.
• public HandlerCallback accept_charset (string charsets, owned ForwardCallback<string> forward = forward)
  Negotiate a 'Accept-Charset' header.
• public HandlerCallback accept_encoding (string encodings, owned ForwardCallback<string> forward = forward)
  Negotiate a 'Accept-Encoding' header.
• public HandlerCallback accept_language (string languages, owned ForwardCallback<string> forward = forward)
  Negotiate a 'Accept-Language' header.
• public HandlerCallback accept_ranges (string ranges, owned ForwardCallback<string> forward = forward)
  Negotiate a 'Accept-Range' header.
• public HandlerCallback accept_transfer_encoding (string encodings, owned ForwardCallback<string> forward = forward)
  Negotiate a 'TE' header.
• public HandlerCallback negotiate (string header_name, string expectations, owned ForwardCallback<string> forward = forward, EqualFunc<string> match = ( EqualFunc < string >) str_case_equal)
  Negotiate a HTTP header against a set of expectations.
• ServerSentEvents - Middleware and utilities to produce server-sent events.

Delegates:

• public delegate void EventStreamCallback (Request request, owned SendEventCallback send_event, Context context) throws Error
  Create a context for sending SSE messages.
• public delegate void SendEventCallback (string? event, string data, string? id = null, TimeSpan? retry = null) throws Error
  Send an message over the body stream.

Methods:

• public HandlerCallback stream_events (owned EventStreamCallback context)
  Middleware that create a context for sending Server-Sent Events.
• Static - Utilities to serve static resources.

Enums:

• ServeFlags - Flags used to enble or disable options for serving static resources.

Methods:

• public HandlerCallback serve_from_file (File root, ServeFlags serve_flags = NONE, ForwardCallback<File> forward = forward)
  Serve static files relative to a given root.
• public HandlerCallback serve_from_path (string path, ServeFlags serve_flags = NONE, owned ForwardCallback<File> forward = forward)
