Trait EnsureAddressOrigin

pub trait EnsureAddressOrigin<OuterOrigin> {
    type Success;

    // Required method
    fn try_address_origin(
        address: &H160,
        origin: OuterOrigin,
    ) -> Result<Self::Success, OuterOrigin>;

    // Provided method

        origin: OuterOrigin,
    ) -> Result<Self::Success, BadOrigin> { ... }
}

Required Associated Types

type Success

Success return type.

Required Methods

fn try_address_origin( address: &H160, origin: OuterOrigin, ) -> Result<Self::Success, OuterOrigin>

Try with origin.

Provided Methods

fn ensure_address_origin( address: &H160, origin: OuterOrigin, ) -> Result<Self::Success, BadOrigin>

Perform the origin check.

Dyn Compatibility

This trait is not dyn compatible.

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