Required Methods§
Sourcefn try_origin(
o: OuterOrigin,
a: &Argument,
) -> Result<Self::Success, OuterOrigin>
fn try_origin( o: OuterOrigin, a: &Argument, ) -> Result<Self::Success, OuterOrigin>
Perform the origin check, returning the origin value if unsuccessful. This allows chaining.

This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
