        part: BodyPart,
    },
}

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

Parent

The consensus system of which the context is a member and state-wise super-set.

NOTE: This item is not a sub-consensus item: a consensus system may not identify itself trustlessly as a location that includes this junction.

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 fn is_parent(&self) -> bool

Returns true if this junction is a Parent item.

pub fn is_interior(&self) -> bool

Returns true if this junction can be considered an interior part of its context. This is generally true, except for the Parent item.

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

Formats the value using the given formatter.

impl Decode for Junction

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

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: Output + ?Sized>(
    &self,
    __codec_dest_edqy: &mut __CodecOutputEdqy
)

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 Junction

fn from(v1: Junction) -> Junction

Converts to this type from the input type.

impl From<Junction> for MultiLocation

fn from(x: Junction) -> Self

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.

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

impl PartialEq<Junction> for Junction

fn eq(&self, other: &Junction) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
