Methods available on frame_system::Config::Origin.

Associated Types

type Call

Runtime call type, as in frame_system::Config::Call

type PalletsOrigin

The caller origin, overarching type of all pallets origins.

type AccountId

The AccountId used across the system.

Required methods

fn add_filter(&mut self, filter: impl Fn(&Self::Call) -> bool + 'static)

Add a filter to the origin.

fn reset_filter(&mut self)

Reset origin filters to default one, i.e frame_system::Config::BaseCallFilter.

fn set_caller_from(&mut self, other: impl Into<Self>)

Replace the caller with caller from the other origin

fn filter_call(&self, call: &Self::Call) -> bool

Filter the call, if false then call is filtered out.

fn caller(&self) -> &Self::PalletsOrigin

Get the caller.

fn try_with_caller<R>(
    self,
    f: impl FnOnce(Self::PalletsOrigin) -> Result<R, Self::PalletsOrigin>
) -> Result<R, Self>

Do something with the caller, consuming self but returning it if the caller was unused.

fn none() -> Self

Create with system none origin and frame-system::Config::BaseCallFilter.

fn root() -> Self

Create with system root origin and no filter.

fn signed(by: Self::AccountId) -> Self

Create with system signed origin and frame-system::Config::BaseCallFilter.
