Struct AncestryProof

pub struct AncestryProof<Hash> {
    pub prev_peaks: Vec<Hash>,
    pub prev_leaf_count: u64,
    pub leaf_count: NodeIndex,
    pub items: Vec<(u64, Hash)>,
}

An MMR ancestry proof for a prior mmr root.

Fields

prev_peaks: Vec<Hash>

Peaks of the ancestor’s mmr

prev_leaf_count: u64

Number of leaves in the ancestor’s MMR.

leaf_count: NodeIndex

Number of leaves in MMR, when the proof was generated.

items: Vec<(u64, Hash)>

Proof elements (positions and hashes of siblings of inner nodes on the path to the previous peaks).

Trait Implementations

impl<Hash: Clone> Clone for AncestryProof<Hash>

fn clone(&self) -> AncestryProof<Hash>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Hash> Debug for AncestryProof<Hash>

where Hash: Debug,

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

Formats the value using the given formatter.

impl<Hash> Decode for AncestryProof<Hash>

where Vec<Hash>: Decode, Vec<(u64, Hash)>: Decode,

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<Hash> Encode for AncestryProof<Hash>

where Vec<Hash>: Encode, Vec<(u64, Hash)>: Encode,

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<Hash: PartialEq> PartialEq for AncestryProof<Hash>

fn eq(&self, other: &AncestryProof<Hash>) -> 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<Hash> TypeInfo for AncestryProof<Hash>

where Vec<Hash>: TypeInfo + 'static, Vec<(u64, Hash)>: TypeInfo + 'static, Hash: TypeInfo + 'static,

type Identity = AncestryProof<Hash>

The type identifying for which type info is provided.

fn type_info() -> Type
