pub enum ParamFrom {
Path,
Extra,
Request,
}Expand description
Where a route parameter’s value comes from at dispatch.
★ THREE-STATE ON PURPOSE, replacing a from_path: bool. A boolean could only ever ask “path or
not”, so the arrival of a third source had nowhere to go but a second boolean beside the first —
and a pair of booleans has four states of which one is nonsense. Making the question total means
a fourth source cannot be added without every match on it failing to compile, which is the
same discipline is_void and action_verb_tier_lock already hold elsewhere.
Variants§
Path
A :name segment of the route’s own path pattern.
Extra
The query string, or the request body for a method that carries one.
Request
The whole request, bound as-is.

&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
