Trait for read-write buffer access with optimized primitive writes.

All write methods use little-endian byte order as per SBE specification.

Required Methods

fn as_mut_slice(&mut self) -> &mut [u8]

Returns the buffer as a mutable byte slice.

Provided Methods

fn put_u8(&mut self, offset: usize, value: u8)

Writes a u8 at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_i8(&mut self, offset: usize, value: i8)

Writes an i8 at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_u16_le(&mut self, offset: usize, value: u16)

Writes a u16 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_i16_le(&mut self, offset: usize, value: i16)

Writes an i16 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_u32_le(&mut self, offset: usize, value: u32)

Writes a u32 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_i32_le(&mut self, offset: usize, value: i32)

Writes an i32 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_u64_le(&mut self, offset: usize, value: u64)

Writes a u64 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_i64_le(&mut self, offset: usize, value: i64)

Writes an i64 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_f32_le(&mut self, offset: usize, value: f32)

Writes an f32 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_f64_le(&mut self, offset: usize, value: f64)

Writes an f64 in little-endian at the given offset.

Arguments

• offset - Byte offset to write to
• value - Value to write

fn put_bytes(&mut self, offset: usize, src: &[u8])

Writes a byte slice at the given offset.

Arguments

• offset - Byte offset to write to
• src - Source bytes to copy

fn put_str(&mut self, offset: usize, value: &str, max_len: usize)

Writes a string to a fixed-length field, padding with nulls.

Arguments

• offset - Byte offset to write to
• value - String value to write
• max_len - Maximum field length in bytes

fn zero(&mut self, offset: usize, len: usize)

Fills a range with zeros.

Arguments

• offset - Byte offset to start from
• len - Number of bytes to zero

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
