Expand description
Non-parent junctions that can be constructed, up to the length of 8. This specific Junctions
implementation uses a Rust enum
in order to make pattern matching easier.
Parent junctions cannot be constructed with this type. Refer to MultiLocation
for
instructions on constructing parent junctions.
Variants
The interpreting consensus system.
X1(Junction)
A relative path comprising 1 junction.
Tuple Fields of X1
0: Junction
A relative path comprising 2 junctions.
A relative path comprising 3 junctions.
A relative path comprising 4 junctions.
A relative path comprising 5 junctions.
A relative path comprising 6 junctions.
A relative path comprising 7 junctions.
A relative path comprising 8 junctions.

Implementations
Convert self
into a MultiLocation
containing 0 parents.
Similar to Into::into
, except that this method can be used in a const evaluation context.
Convert self
into a MultiLocation
containing n
parents.
Similar to Self::into
, with the added ability to specify the number of parent junctions.
Returns first junction, or None
if the location is empty.
Returns last junction, or None
if the location is empty.
Splits off the first junction, returning the remaining suffix (first item in tuple) and the first element
(second item in tuple) or None
if it was empty.
Splits off the last junction, returning the remaining prefix (first item in tuple) and the last element
(second item in tuple) or None
if it was empty.
Removes the first element from self
, returning it (or None
if it was empty).
Removes the last element from self
, returning it (or None
if it was empty).
Mutates self
to be appended with new
or returns an Err
with new
if would overflow.
Mutates self
to be prepended with new
or returns an Err
with new
if would overflow.
Consumes self
and returns a Junctions
suffixed with new
, or an Err
with the
original value of self
and new
in case of overflow.
Consumes self
and returns a Junctions
prefixed with new
, or an Err
with the
original value of self
and new
in case of overflow.
Returns the junction at index i
, or None
if the location doesn’t contain that many elements.
Returns a mutable reference to the junction at index i
, or None
if the location doesn’t contain that many
elements.
👎 Deprecated: Please use iter().rev()
Please use iter().rev()
Returns a reference iterator over the junctions in reverse.
👎 Deprecated: Please use into_iter().rev()
Please use into_iter().rev()
Consumes self
and returns an iterator over the junctions in reverse.
Ensures that self begins with prefix
and that it has a single Junction
item following.
If so, returns a reference to this Junction
item.
Example
let mut m = X3(Parachain(2), PalletInstance(3), OnlyChild);
assert_eq!(m.match_and_split(&X2(Parachain(2), PalletInstance(3))), Some(&OnlyChild));
assert_eq!(m.match_and_split(&X1(Parachain(2))), None);
