Struct CheckOrigin

pub struct CheckOrigin<RuntimeOrigin, Inner = NoParams>(pub RuntimeOrigin, pub Inner);
Expand description

The CheckOrigin is a strategy that accepts a runtime origin and the Inner strategy.

It is meant to be used when the origin check should be performed prior to the Inner strategy execution.

The CheckOrigin implements all potentially state-mutating strategies that the Inner implements.

Implementations§

§

impl<RuntimeOrigin, Inner> CheckOrigin<RuntimeOrigin, Inner>
where Inner: Default,

pub fn check(origin: RuntimeOrigin) -> CheckOrigin<RuntimeOrigin, Inner>

This function creates a CheckOrigin strategy. The operation that accepts it must check if the provided origin is allowed to perform it.

If so, the operation must, in turn, proceed according to the default value of the Inner strategy.

§

impl<RuntimeOrigin, Inner> CheckOrigin<RuntimeOrigin, Inner>

pub fn new( origin: RuntimeOrigin, inner: Inner, ) -> CheckOrigin<RuntimeOrigin, Inner>

This function creates a CheckOrigin strategy. The operation that accepts it must check if the provided origin is allowed to perform it.

If so, the operation must, in turn, proceed according to the provided value of the Inner strategy.
