}

A single item in a path to describe the relative location of a consensus system.

Each item assumes a pre-existing location as its context and is defined in terms of it.

Variants

Parachain(u32)

An indexed parachain belonging to and operated by the context.

Generally used when the context is a Polkadot Relay-chain.

AccountId32

Fields

network: NetworkId

id: [u8; 32]

A 32-byte identifier for an account of a specific network that is respected as a sovereign endpoint within the context.

Generally used when the context is a Substrate-based chain.

AccountIndex64

Fields

network: NetworkId

index: u64

An 8-byte index for an account of a specific network that is respected as a sovereign endpoint within the context.

May be used when the context is a Frame-based chain and includes e.g. an indices pallet.

AccountKey20

Fields

network: NetworkId

key: [u8; 20]

A 20-byte identifier for an account of a specific network that is respected as a sovereign endpoint within the context.

May be used when the context is an Ethereum or Bitcoin chain or smart-contract.

PalletInstance(u8)

An instanced, indexed pallet that forms a constituent part of the context.

Generally used when the context is a Frame-based chain.

GeneralIndex(u128)

A non-descript index within the context location.

Usage will vary widely owing to its generality.

NOTE: Try to avoid using this and instead use a more specific item.

GeneralKey(WeakBoundedVec<u8, ConstU32<32>>)

A nondescript datum acting as a key within the context location.

Usage will vary widely owing to its generality.

NOTE: Try to avoid using this and instead use a more specific item.

OnlyChild

The unambiguous child.

Not currently used except as a fallback when deriving ancestry.

Plurality

Fields

id: BodyId

part: BodyPart

A pluralistic body existing within consensus.

Typical to be used to represent a governance origin of a chain, but could in principle be used to represent things such as multisigs also.

Implementations

impl Junction

pub const fn into(self) -> MultiLocation

Convert self into a MultiLocation containing 0 parents.

Similar to Into::into, except that this method can be used in a const evaluation context.

pub const fn into_exterior(self, n: u8) -> MultiLocation

Convert self into a MultiLocation containing n parents.

Similar to Self::into, with the added ability to specify the number of parent junctions.

Trait Implementations

impl Clone for Junction

fn clone(&self) -> Junction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Junction

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Decode for Junction

fn decode<__CodecInputEdqy>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Junction, Error>where
    __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where
    I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for Junction

fn encode_to<__CodecOutputEdqy>(&self, __codec_dest_edqy: &mut __CodecOutputEdqy)where
    __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<Junction> for MultiLocation

fn from(x: Junction) -> MultiLocation

Converts to this type from the input type.

impl MaxEncodedLen for Junction

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl Ord for Junction

fn cmp(&self, other: &Junction) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.
