Enum Resolution 

Source 
#[non_exhaustive]
pub enum Resolution {
    Op(ResolvedRoute),
    NotAnOp,
    MethodNotAllowed(Vec<Method>),
    Unresolved,
}
Expand description

A BindingResolver’s answer.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Op(ResolvedRoute)

A generated op: the request is opened, verified, or refused according to the policy.

§

NotAnOp

A route the resolver recognises and knows is not an op, such as an RPC op id that no generated op can have (/rpc/%62atch, decision B2). A plain request passes through (the router answers it, a 404), a COSE one is refused with the unsigned 415.

§

MethodNotAllowed(Vec<Method>)

A generated route, but not for this method: the router answers 405 with these methods in Allow. Passes through, unless the policy’s unresolved_mode is Required and the route is not allow-listed: then the layer answers the 405 itself, so a hand-written handler for another method on a generated path cannot run unsigned (decision S2).

§

Unresolved

A route the resolver does not know. With no matched route (a 404) it passes through; with one, under a Required unresolved_mode and not allow-listed, the layer fails closed with a 500 (S2).

§

fn quirk(&self, value: Quirk) -> Painted<&T>
