ParamContext

Struct ParamContext

pub struct ParamContext { /* private fields */ }

Available on crate feature client-router only.

Expand description

Context for parameter extraction.

Contains both named parameters (for backward compatibility) and ordered parameter values (for tuple extraction).

Implementations§

impl ParamContext

pub fn new( params: HashMap<String, String>, param_values: Vec<String>, ) -> ParamContext

Available on crate feature test only.

Creates a new parameter context.

pub fn with_path(self, path: String) -> ParamContext

Available on crate feature test only.

Creates a new parameter context with an attached matched path.

Used by ClientRouter::render_current when dispatching a ClientRouter::page handler so RouteContext::path exposes the matched path without any query string.

pub fn with_query(self, query: Option<String>) -> ParamContext

Available on crate feature test only.

Creates a new parameter context with an attached query string.

Used by ClientRouter::render_current when dispatching a ClientRouter::page handler so QueryParam<T> extractors can see the captured query.

pub fn params(&self) -> &HashMap<String, String>

Available on crate feature test only.

Returns the named-parameter map (path parameters captured by the route pattern, keyed by their {name} placeholder).

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

Available on crate feature test only.

Returns the matched path (without the query string), if present.

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

Available on crate feature test only.

Returns the raw query string (without the leading ?), if any.

pub fn len(&self) -> usize

Available on crate feature test only.

Returns the number of parameters.

pub fn is_empty(&self) -> bool

Available on crate feature test only.

Returns whether there are no parameters.
