Enum SpecMsgKind 

pub enum SpecMsgKind {
    Signal(SpecMsgSignal),
    Data(Vec<u8>),
}

The payload of every channel-stream MMR leaf: protocol signalling or userspace data. The transport acts only on Signal vs Data (window accounting, pallet-internal consumption); demultiplexing within Data is an upper-layer convention.

Variants

Signal(SpecMsgSignal)

Channel lifecycle signalling. Emitted and consumed by the pallet, never by applications; window-counted and ordered like any other leaf.

Data(Vec<u8>)

Userspace payload bytes, delivered in order. The sender STF bounds the encoded leaf, not these bytes, by crate::message::MAX_SPECULATIVE_MESSAGE_LEN. The variant byte and the compact length take up to 5 of it, so data holds 5 bytes less.

Trait Implementations

impl Clone for SpecMsgKind

fn clone(&self) -> SpecMsgKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpecMsgKind

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

Formats the value using the given formatter.

impl Decode for SpecMsgKind

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

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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 SpecMsgKind

fn size_hint(&self) -> usize

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

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

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where 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 PartialEq for SpecMsgKind

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TypeInfo for SpecMsgKind

type Identity = SpecMsgKind

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl DecodeWithMemTracking for SpecMsgKind

impl EncodeLike for SpecMsgKind
