Struct pallet_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.

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

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for EncodableOpaqueLeaf

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: FnOnce(&[u8]) -> R>(&self, f: F) -> R
