Required Methods§
sourcefn try_origin(
o: OuterOrigin,
a: &Argument
) -> Result<Self::Success, OuterOrigin>
fn try_origin( o: OuterOrigin, a: &Argument ) -> Result<Self::Success, OuterOrigin>
Perform the origin check, returning the origin value if unsuccessful. This allows chaining.
sourcefn try_successful_origin(a: &Argument) -> Result<OuterOrigin, ()>
fn try_successful_origin(a: &Argument) -> Result<OuterOrigin, ()>
Attempt to get an outer origin capable of passing try_origin check. May return Err if it
is impossible.
