Trait Implementations

impl<U: Clone> Clone for Permissive<U>

fn clone(&self) -> Permissive<U>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<U: Debug> Debug for Permissive<U>

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

Formats the value using the given formatter.

impl<U: PartialEq> PartialEq for Permissive<U>

fn eq(&self, other: &Permissive<U>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<U: Switch> Switch for Permissive<U>

fn from_route_part<STATE>( part: String, state: Option<STATE>, ) -> (Option<Self>, Option<STATE>)

Option is very permissive in what is allowed.

fn build_route_section<STATE>(self, route: &mut String) -> Option<STATE>

Build part of a route from itself.

fn key_not_available() -> Option<Self>

Called when the key (the named capture group) can’t be located. Instead of failing outright, a default item can be provided instead.

fn switch<STATE>(route: Route<STATE>) -> Option<Self>

Based on a route, possibly produce an itself.
