Extends Write with methods for reading LEB128-encoded integers.

Provided Methods

fn write_int<T: Varint>(&mut self, x: T) -> Result<usize>

Writes a LEB128-encoded integer and returns the number of bytes written.

fn write_u8(&mut self, x: u8) -> Result<usize>

Writes a LEB128-encoded u8 and returns the number of bytes written.

fn write_u16(&mut self, x: u16) -> Result<usize>

Writes a LEB128-encoded u16 and returns the number of bytes written.

fn write_u32(&mut self, x: u32) -> Result<usize>

Writes a LEB128-encoded u32 and returns the number of bytes written.

fn write_u64(&mut self, x: u64) -> Result<usize>

Writes a LEB128-encoded u64 and returns the number of bytes written.

fn write_u128(&mut self, x: u128) -> Result<usize>

Writes a LEB128-encoded u128 and returns the number of bytes written.

fn write_usize(&mut self, x: usize) -> Result<usize>

Writes a LEB128-encoded usize and returns the number of bytes written.

fn write_i8(&mut self, x: i8) -> Result<usize>

Writes a LEB128-encoded i8 and returns the number of bytes written.

fn write_i16(&mut self, x: i16) -> Result<usize>

Writes a LEB128-encoded i16 and returns the number of bytes written.

fn write_i32(&mut self, x: i32) -> Result<usize>

Writes a LEB128-encoded i32 and returns the number of bytes written.

fn write_i64(&mut self, x: i64) -> Result<usize>

Writes a LEB128-encoded i64 and returns the number of bytes written.

fn write_i128(&mut self, x: i128) -> Result<usize>

Writes a LEB128-encoded i128 and returns the number of bytes written.

fn write_isize(&mut self, x: isize) -> Result<usize>

Writes a LEB128-encoded isize and returns the number of bytes written.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
