Trait frame_support::traits::EnsureOrigin

pub trait EnsureOrigin<OuterOrigin> {
    type Success;

    fn try_origin(o: OuterOrigin) -> Result<Self::Success, OuterOrigin>;

    fn ensure_origin(o: OuterOrigin) -> Result<Self::Success, BadOrigin> { ... }
    fn successful_origin() -> OuterOrigin { ... }
    fn try_successful_origin() -> Result<OuterOrigin, ()> { ... }
}

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

Required Associated Types

type Success

A return type.

Required Methods

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

Perform the origin check.

Provided Methods

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

Perform the origin check.

fn successful_origin() -> OuterOrigin

Returns an outer origin capable of passing try_origin check.

NOTE: This should generally NOT be reimplemented. Instead implement try_successful_origin.

** Should be used for benchmarking only!!! **

fn try_successful_origin() -> Result<OuterOrigin, ()>

Attept to get an outer origin capable of passing try_origin check. May return Err if it is impossible. Default implementation just uses successful_origin().

** Should be used for benchmarking only!!! **
