type 'a t

'a t represents a path parameter of type 'a.

type 'a router
val return : 'a -> 'a t

return v is a path param parser that always returns v.

val apply : ( 'a -> 'b ) t -> 'a t -> 'b t

apply f t applies a function f that is wrapped inside a 'a t context to a path param parser. f <*> p is the same as f >>= fun f -> map ~f p

val s : string -> string t

s word returns a path parser that matches word exactly.

val int : int t

int parses a path parmeter and succeeds if its an integer.

val int32 : int32 t

int32 parses a path parameter and succeeds if its a valid 32 bit integer.

val int64 : int64 t

int64 parses a path parameter and succeeds if its a valid 64 bit integer.

val bool : bool t

bool parses a path parameter and succeeds if its either "true" or "false".

val str : string t

str parses a path param and returns it as a string.

val empty : unit t

empty matches an empty target. This can be used to match against "/".

val choice : 'a t list -> 'a t

choice accepts a list of route parsers and returns the first one that matches.

val with_method : (Method.t * 'a t) list -> 'a router

choose accepts a list of path param parsers and converts them to a router.

val match' : 'a t -> string -> 'a option

match' takes a route parser and runs it against the provided target url.

val match_with_method : 'a router -> target:string -> meth:Method.t -> 'a option

match_with_method is used to run the router. It accepts a target url string, HTTP method verb a request of any type (which is forwarded as the last parameter to the handler functions). If a route matches it runs the attached handler and returns the result.
