pub struct TryMapSuccess<Orig, Mutator>(/* private fields */);Expand description
A derivative EnsureOrigin implementation. It mutates the Success result of an Original
implementation with a given Mutator, allowing the possibility of an error to be returned
from the mutator.
NOTE: This is strictly worse performance than MapSuccess since it clones the original origin
value. If possible, use MapSuccess instead.

A return type.

Perform the origin check.

Perform the origin check.

fn ensure_origin_or_root(

OuterOrigin: OriginTrait,
The same as
ensure_origin except that Root origin will always pass. This can only be
used if Success has a sensible impl of Default since that will be used in the result.Source§fn try_origin_or_root(
