Struct ibc_proto::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.

pub fn set_prehash_value(&mut self, value: HashOp)

Sets prehash_value to the provided enum value.

pub fn length(&self) -> LengthOp
