A trait to help to write data to a writer.

Required Methods

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

Writes a u8 to the writer.

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

Writes a u16 to the writer in little-endian order.

fn write_u16_be(&mut self, value: u16) -> Result<()>

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

Writes a u32 to the writer in little-endian order.

fn write_u32_be(&mut self, value: u32) -> Result<()>

Writes a u32 to the writer in big-endian order.

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

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

Writes a u128 to the writer in little-endian order.

fn write_u128_be(&mut self, value: u128) -> Result<()>

Writes a u128 to the writer in big-endian order.

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

Writes an i8 to the writer.

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

Writes an i16 to the writer in little-endian order.

fn write_i16_be(&mut self, value: i16) -> Result<()>

Writes an i16 to the writer in big-endian order.

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

Writes an i32 to the writer in little-endian order.

fn write_i32_be(&mut self, value: i32) -> Result<()>

Writes an i32 to the writer in big-endian order.

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

Writes an i64 to the writer in little-endian order.

fn write_i64_be(&mut self, value: i64) -> Result<()>

Writes an i64 to the writer in big-endian order.

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

Writes an i128 to the writer in little-endian order.

fn write_i128_be(&mut self, value: i128) -> Result<()>

Writes an i128 to the writer in big-endian order.

fn write_f32(&mut self, value: f32) -> Result<()>

Writes a f32 to the writer in little-endian order.

fn write_f32_be(&mut self, value: f32) -> Result<()>

Writes a f32 to the writer in big-endian order.

fn write_f64(&mut self, value: f64) -> Result<()>

Writes a f64 to the writer in little-endian order.

fn write_f64_be(&mut self, value: f64) -> Result<()>

Writes a f64 to the writer in big-endian order.

fn write_cstring(&mut self, value: &CString) -> Result<()>

Writes a C-style string (null-terminated) to the writer.

fn write_fstring( &mut self, data: &str, len: usize, encoding: Encoding, padding: u8, truncate: bool, ) -> Result<()>

Writes a C-style string (null-terminated) from the reader with maximum length.

• data is the string data to write.
• len is the maximum length of the string to write. If the string is longer, it will be truncated if truncate is true otherwise an error is returned.
• encoding specifies the encoding to use for the string.
• padding indicates how to pad the string if it’s shorter than len.
• truncate indicates whether to truncate the string if it’s longer than len.

fn write_struct<V: StructPack>( &mut self, value: &V, big: bool, encoding: Encoding, info: &Option<Box<dyn Any>>, ) -> Result<()>

Write a struct to the writer.

fn write_from<R: Read + Seek>( &mut self, reader: &mut R, offset: u64, len: u64, ) -> Result<()>

Writes data from a reader to the writer.

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.
