Struct sp_mmr_primitives::EncodableOpaqueLeaf

pub struct EncodableOpaqueLeaf(pub Vec<u8>);

A type-safe wrapper for the concrete leaf type.

This structure serves merely to avoid passing raw Vec<u8> around. It must be Vec<u8>-encoding compatible.

It is different from OpaqueLeaf, because it does implement Codec and the encoding has to match raw Vec<u8> encoding.

Tuple Fields

0: Vec<u8>

Implementations

impl EncodableOpaqueLeaf

pub fn from_leaf<T: FullLeaf>(leaf: &T) -> Self

Convert a concrete leaf into encodable opaque version.

pub fn from_opaque_leaf(opaque: OpaqueLeaf) -> Self

Given an opaque leaf, make it encodable.

pub fn into_opaque_leaf(self) -> OpaqueLeaf

Try to convert into a OpaqueLeaf.

Trait Implementations

impl Debug for EncodableOpaqueLeaf

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

Formats the value using the given formatter.

impl Decode for EncodableOpaqueLeaf

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 EncodableOpaqueLeaf

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<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback ) -> __CodecOutputReturn

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 EncodableOpaqueLeaf

fn eq(&self, other: &EncodableOpaqueLeaf) -> 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.

impl TypeInfo for EncodableOpaqueLeaf

type Identity = EncodableOpaqueLeaf

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
