Struct grin_core::ser::BinWriter

pub struct BinWriter<'a> { /* private fields */ }

Utility wrapper for an underlying byte Writer. Defines higher level methods to write numbers, byte vectors, hashes, etc.

Implementations

impl<'a> BinWriter<'a>

pub fn new(sink: &'a mut dyn Write, version: ProtocolVersion) -> BinWriter<'a>

Wraps a standard Write in a new BinWriter

pub fn default(sink: &'a mut dyn Write) -> BinWriter<'a>

Constructor for BinWriter with default “local” protocol version.

Trait Implementations

impl<'a> Writer for BinWriter<'a>

fn serialization_mode(&self) -> SerializationMode

The mode this serializer is writing in

fn write_fixed_bytes<T: AsRef<[u8]>>(&mut self, bytes: T) -> Result<(), Error>

Writes a fixed number of bytes. 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: AsRef<[u8]>>(&mut self, bytes: T) -> Result<(), Error>

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

fn write_empty_bytes(&mut self, length: usize) -> Result<(), Error>

Writes a fixed length of “empty” bytes.
