implementation. It mutates the Success
result of an Original
implementation with a given Mutator
.
Trait Implementations§

impl<O, Original: EnsureOrigin<O>, Mutator: Morph<Original::Success>> EnsureOrigin<O> for MapSuccess<Original, Mutator>
source§fn try_origin(o: O) -> Result<Mutator::Outcome, O>
fn try_origin(o: O) -> Result<Mutator::Outcome, O>
Perform the origin check.
source§fn try_successful_origin() -> Result<O, ()>
fn try_successful_origin() -> Result<O, ()>
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()
. Read moresource§fn ensure_origin(o: OuterOrigin) -> Result<Self::Success, BadOrigin>
fn ensure_origin(o: OuterOrigin) -> Result<Self::Success, BadOrigin>
Perform the origin check.
source§fn successful_origin() -> OuterOrigin
fn successful_origin() -> OuterOrigin
Returns an outer origin capable of passing
try_origin
check. Read moreAuto Trait Implementations§
