Struct cosmos_sdk_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.

Implementations

impl LeafOp

pub fn hash(&self) -> HashOp

Returns the enum value of hash, or the default if the field is set to an invalid enum value.

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

Sets hash to the provided enum value.

pub fn prehash_key(&self) -> HashOp

Returns the enum value of prehash_key, or the default if the field is set to an invalid enum value.

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

Sets prehash_key to the provided enum value.

pub fn prehash_value(&self) -> HashOp

Returns the enum value of prehash_value, or the default if the field is set to an invalid enum value.

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

Sets prehash_value to the provided enum value.

pub fn length(&self) -> LengthOp

Returns the enum value of length, or the default if the field is set to an invalid enum value.

pub fn set_length(&mut self, value: LengthOp)

Sets length to the provided enum value.

Trait Implementations

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 Default for LeafOp

fn default() -> Self

Returns the “default value” for a type.

impl Message for LeafOp

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, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

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

where B: BufMut, Self: Sized,

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

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

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

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

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

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

where B: Buf, Self: Sized,

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

impl Name for LeafOp

const NAME: &'static str = "LeafOp"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "ics23"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing with the [Any] type.

impl PartialEq 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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
