Struct mohan::hash::HashWriter

pub struct HashWriter { /* fields omitted */ }

Serializer that outputs a hash of the serialized object

Methods

impl HashWriter

pub fn finalize(&mut self, output: &mut [u8])

Consume the HashWriter, outputting its current hash into a 32-byte array

pub fn into_hash(&mut self) -> H256

Consume the HashWriter, outputting a Hash corresponding to its current state

Trait Implementations

impl Default for HashWriter

fn default() -> HashWriter

Returns the "default value" for a type.

impl Writer for HashWriter

fn serialization_mode(&self) -> SerializationMode

The mode this serializer is writing in

fn write_fixed_bytes<T: AsFixedBytes>(&mut self, b32: &T) -> Result<(), Error>

Writes a fixed number of bytes from something that can turn itself into a &[u8]. The reader is expected to know the actual length on read.

fn protocol_version(&self) -> ProtocolVersion

Protocol version for version specific serialization rules.

fn write_u8(&mut self, n: u8) -> Result<(), Error>

Writes a u8 as bytes

fn write_u16(&mut self, n: u16) -> Result<(), Error>

Writes a u16 as bytes

fn write_u32(&mut self, n: u32) -> Result<(), Error>

Writes a u32 as bytes

fn write_i32(&mut self, n: i32) -> Result<(), Error>

Writes a u32 as bytes

fn write_u64(&mut self, n: u64) -> Result<(), Error>

Writes a u64 as bytes

fn write_i64(&mut self, n: i64) -> Result<(), Error>

Writes a i64 as bytes

fn write_bytes<T: AsFixedBytes>(&mut self, bytes: &T) -> Result<(), Error>

Writes a variable number of bytes. The length is encoded as a 64-bit prefix.
