Struct BinaryWriter

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

Write to a stream.

Implementations

impl<'a> BinaryWriter<'a>

pub fn new(stream: &'a mut impl WriteStream, endian: Endian) -> Self

Create a binary writer with the given endianness.

pub fn write_string<S: AsRef<str>>(&mut self, value: S) -> Result<usize>

Write a length-prefixed String to the stream.

The length of the String is written as a usize unless the wasm32 or string_len_u32 feature is enabled in which case the length is a u32.

pub fn write_7bit_encoded_len_string<S: AsRef<str>>( &mut self, value: S, ) -> Result<usize>

Write a 7bit encoded length-prefixed String to the stream.

The length of the String is written as a 7bit encoded usize unless the wasm32 or string_len_u32 feature is enabled in which case the length is a 7bit encoded u32.

pub fn write_char<V: Borrow<char>>(&mut self, v: V) -> Result<usize>

Write a character to the stream.

pub fn write_bool<V: Borrow<bool>>(&mut self, value: V) -> Result<usize>

Write a bool to the stream.

pub fn write_f32<V: Borrow<f32>>(&mut self, value: V) -> Result<usize>

Write a f32 to the stream.

pub fn write_f64<V: Borrow<f64>>(&mut self, value: V) -> Result<usize>

Write a f64 to the stream.

pub fn write_isize<V: Borrow<isize>>(&mut self, value: V) -> Result<usize>

Write an isize to the stream.

pub fn write_usize<V: Borrow<usize>>(&mut self, value: V) -> Result<usize>

Write a usize to the stream.

pub fn write_u64<V: Borrow<u64>>(&mut self, value: V) -> Result<usize>

Write a u64 to the stream.

pub fn write_i64<V: Borrow<i64>>(&mut self, value: V) -> Result<usize>

Write an i64 to the stream.

pub fn write_u32<V: Borrow<u32>>(&mut self, value: V) -> Result<usize>

Write a u32 to the stream.

pub fn write_i32<V: Borrow<i32>>(&mut self, value: V) -> Result<usize>

Write an i32 to the stream.

pub fn write_u16<V: Borrow<u16>>(&mut self, value: V) -> Result<usize>

Write a u16 to the stream.

pub fn write_i16<V: Borrow<i16>>(&mut self, value: V) -> Result<usize>

Write an i16 to the stream.

pub fn write_u8<V: Borrow<u8>>(&mut self, value: V) -> Result<usize>

Write a u8 to the stream.

pub fn write_i8<V: Borrow<i8>>(&mut self, value: V) -> Result<usize>

Write an i8 to the stream.

pub fn write_bytes<B: AsRef<[u8]>>(&mut self, data: B) -> Result<usize>

Write a byte buffer to the stream.

pub fn write_bytes_with_value( &mut self, count: usize, fill_value: u8, ) -> Result<usize>

Write a byte buffer to the stream.

pub fn write_7bit_encoded_i32(&mut self, value: i32) -> Result<usize>

Write 7bit encoded i32 to the stream

pub fn write_7bit_encoded_u32(&mut self, value: u32) -> Result<usize>

Write 7bit encoded u32 to the stream

pub fn write_7bit_encoded_usize(&mut self, value: usize) -> Result<usize>

Write 7bit encoded usize to the stream

pub fn swap_endianness(&mut self)

Swap endianness to allow for reversing the writing mid stream

Trait Implementations

impl<'a> SeekStream for BinaryWriter<'a>
