Struct StreamsRoot 

pub struct StreamsRoot(pub H256);

The sender’s per-block stream commitment root. Defined relay-side and re-exported here. Root of a sender’s stream commitment tree: a compact binary trie keyed by the 8-byte StreamId encoding, with the streams’ MMR roots as leaves.

A newtype over Hash, distinct from an MMR root so the two cannot be confused. The relay chain treats it as opaque; the tree and its proofs are in cumulus-primitives-spec-messaging::streams_root.

Trait Implementations

impl Clone for StreamsRoot

fn clone(&self) -> StreamsRoot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamsRoot

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

Formats the value using the given formatter.

impl Decode for StreamsRoot

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

where __CodecInputEdqy: Input,

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 Default for StreamsRoot

fn default() -> StreamsRoot

Returns the “default value” for a type.

impl Encode for StreamsRoot

fn size_hint(&self) -> usize

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

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 encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

where __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn,

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Hash for StreamsRoot

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MaxEncodedLen for StreamsRoot

fn max_encoded_len() -> usize

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

impl PartialEq for StreamsRoot

fn eq(&self, other: &StreamsRoot) -> 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 StreamsRoot

type Identity = StreamsRoot

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl Copy for StreamsRoot

impl DecodeWithMemTracking for StreamsRoot

impl EncodeLike for StreamsRoot

impl Eq for StreamsRoot

impl StructuralPartialEq for StreamsRoot
