Struct CheckOrigin

Source 
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§

Source§

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

Source

pub fn check(origin: RuntimeOrigin) -> Self

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.

Source§

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

Source

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

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.
