Struct match_request::Params

pub struct Params { /* fields omitted */ }

Parameters matched by a URL pattern.

Implementations

impl Params

pub fn get<'a>(&'a self, name: &str) -> Option<&'a str>

Gets a named parameter from the matched pattern.

For example, the pattern /post/:id would produce a named parameter that can be retrieved using get("id").

pub fn tail(&self) -> Option<&str>

If the pattern included /*, this is the rest of the path from that point (including the leading forward-slash).

For example, the path /foo/bar applied to the pattern /foo/* would result in a tail() value of Some("/bar")). If the pattern did not include /*, this method returns None.

pub fn len(&self) -> usize

The total number of matched parameters (including the tail, if any).

pub fn is_empty(&self) -> bool

Returns true if the pattern matched no named parameters and no tail, false otherwise.

pub fn from_captures<'t>(names: CaptureNames, caps: Captures<'t>) -> Self

Creates a Params struct from the provided Regex capture names and matches (the tail capture should be named "__tail__").

You should not need to call this directly.
