Expand description

Some sort of check on the origin is performed by this object.

Required Associated Types§

source

type Success

A return type.

Required Methods§

source

fn try_origin( o: OuterOrigin, a: &Argument, ) -> Result<Self::Success, OuterOrigin>

Perform the origin check, returning the origin value if unsuccessful. This allows chaining.

Provided Methods§

source

fn ensure_origin( o: OuterOrigin, a: &Argument, ) -> Result<Self::Success, BadOrigin>

Perform the origin check.

Object Safety§

This trait is not object safe.
