Module field 

Field trait and implementations for zero-copy field access.

This module provides the abstraction for reading and writing protocol fields directly from/to raw packet buffers at specific offsets.

Structs

BytesField

A variable-length byte field

FieldDesc

Describes a field’s position and type within a protocol header.

MacAddress

A 6-byte MAC address with display and parsing support.

Enums

FieldError

Errors that can occur during field operations.

FieldType

Supported field types for dynamic access.

FieldValue

A dynamically-typed field value.

Traits

Field

Trait for reading/writing protocol fields from raw buffers.

Functions

read_bits_be

Read arbitrary number of bits from a byte buffer at a bit offset. bit_offset is the starting bit position (0 = MSB of first byte). num_bits is 1..=64. Returns the value right-aligned in a u64.

read_bits_le

Read bits in little-endian bit order (LSB of first byte = bit 0).

read_i8

read_i16_be

read_i32_be

read_i64_be

read_u16_le

read_u24_be

read_u24_le

read_u32_le

read_u64_le

write_bits_be

Write arbitrary number of bits to a byte buffer at a bit offset. bit_offset is the starting bit position (0 = MSB of first byte). num_bits is 1..=64. value is right-aligned.

write_bits_le

Write bits in little-endian bit order (LSB of first byte = bit 0).
