Struct ics23::LeafOp

pub struct LeafOp {
    pub hash: i32,
    pub prehash_key: i32,
    pub prehash_value: i32,
    pub length: i32,
    pub prefix: Vec<u8>,
}

LeafOp represents the raw key-value data we wish to prove, and must be flexible to represent the internal transformation from the original key-value pairs into the basis hash, for many existing merkle trees.

key and value are passed in. So that the signature of this operation is: leafOp(key, value) -> output

To process this, first prehash the keys and values if needed (ANY means no hash in this case): hkey = prehashKey(key) hvalue = prehashValue(value)

Then combine the bytes, and hash it output = hash(prefix || length(hkey) || hkey || length(hvalue) || hvalue)

Fields

hash: i32

prehash_key: i32

prehash_value: i32

length: i32

prefix: Vec<u8>

prefix is a fixed bytes that may optionally be included at the beginning to differentiate a leaf node from an inner node.

Trait Implementations

impl PartialEq<LeafOp> for LeafOp

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Default for LeafOp

fn default() -> LeafOp

Returns the "default value" for a type.

impl Clone for LeafOp

fn clone(&self) -> LeafOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LeafOp

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

Formats the value using the given formatter.

impl Message for LeafOp

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(&mut self, buf: &mut B) -> Result<(), DecodeError> where
    B: Buf, 

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    B: IntoBuf,
    Self: Default, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    B: IntoBuf,
    Self: Default, 

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: IntoBuf, 

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: IntoBuf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.
