Struct PathParams

pub struct PathParams<'server, 'req> { /* private fields */ }

Represents path parameters extracted from the URL path of an HTTP request.

Path parameters are named segments in the URL path that can be extracted and accessed by name. For example, in the path “/users/{id}”, “id” is a path parameter.

Implementations

impl<'server, 'req> PathParams<'server, 'req>

pub fn empty() -> Self

Creates an empty PathParams instance with no parameters

pub fn is_empty(&self) -> bool

Returns true if there are no path parameters

pub fn len(&self) -> usize

Returns the number of path parameters

pub fn get(&self, key: impl AsRef<str>) -> Option<&'req str>

Gets the value of a path parameter by its name Returns None if the parameter doesn’t exist

Trait Implementations

impl<'server, 'req> Clone for PathParams<'server, 'req>

fn clone(&self) -> PathParams<'server, 'req>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'server, 'req> Debug for PathParams<'server, 'req>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'server, 'req> From<Params<'server, 'req>> for PathParams<'server, 'req>

fn from(params: Params<'server, 'req>) -> Self

Converts to this type from the input type.

impl FromRequest for &PathParams<'_, '_>

Implements path parameter extraction for referenced PathParams

This implementation is similar to the owned version but works with references to PathParams. It allows handlers to receive path parameters as references directly from the request context.

type Output<'r> = &'r PathParams<'r, 'r>
