}Expand description
Some sort of check on the origin is performed by this object.
Required Associated Types§
type Success
type Success
A return type.
Required Methods§
fn try_origin(o: OuterOrigin) -> Result<Self::Success, OuterOrigin>
fn try_origin(o: OuterOrigin) -> Result<Self::Success, OuterOrigin>
Perform the origin check.
Provided Methods§
fn ensure_origin(o: OuterOrigin) -> Result<Self::Success, BadOrigin>
fn ensure_origin(o: OuterOrigin) -> Result<Self::Success, BadOrigin>
Perform the origin check.
fn ensure_origin_or_root(
o: OuterOrigin
) -> Result<Option<Self::Success>, BadOrigin>where
OuterOrigin: OriginTrait,
fn ensure_origin_or_root( o: OuterOrigin ) -> Result<Option<Self::Success>, BadOrigin>where 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.
fn try_origin_or_root(
o: OuterOrigin
) -> Result<Option<Self::Success>, OuterOrigin>where
OuterOrigin: OriginTrait,
fn try_origin_or_root( o: OuterOrigin ) -> Result<Option<Self::Success>, OuterOrigin>where OuterOrigin: OriginTrait,
The same as try_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.
