Trait for read-only buffer access with optimized primitive reads.

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

Required Methods

fn as_slice(&self) -> &[u8]

Returns the buffer as a byte slice.

fn len(&self) -> usize

Returns the length of the buffer in bytes.

Provided Methods

fn is_empty(&self) -> bool

Returns true if the buffer is empty.

fn get_u8(&self, offset: usize) -> u8

Reads a u8 at the given offset.

Arguments

• offset - Byte offset to read from

fn get_i8(&self, offset: usize) -> i8

Reads an i8 at the given offset.

Arguments

• offset - Byte offset to read from

fn get_u16_le(&self, offset: usize) -> u16

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

Arguments

• offset - Byte offset to read from

fn get_i16_le(&self, offset: usize) -> i16

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

Arguments

• offset - Byte offset to read from

fn get_u32_le(&self, offset: usize) -> u32

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

Arguments

• offset - Byte offset to read from

fn get_i32_le(&self, offset: usize) -> i32

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

Arguments

• offset - Byte offset to read from

fn get_u64_le(&self, offset: usize) -> u64

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

Arguments

• offset - Byte offset to read from

fn get_i64_le(&self, offset: usize) -> i64

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

Arguments

• offset - Byte offset to read from

fn get_f32_le(&self, offset: usize) -> f32

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

Arguments

• offset - Byte offset to read from

fn get_f64_le(&self, offset: usize) -> f64

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

Arguments

• offset - Byte offset to read from

fn get_bytes(&self, offset: usize, len: usize) -> &[u8]

Returns a slice of bytes at the given offset and length.

Arguments

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

fn get_str(&self, offset: usize, len: usize) -> &str

Reads a fixed-length character array as a string slice. Trims null bytes from the end.

Arguments

• offset - Byte offset to start from
• len - Maximum length of the string
