Struct Bitmap 

pub struct Bitmap { /* private fields */ }

Available on crate feature alloc only.

Bitmap for tracking present fields (supports up to 192 fields)

Implementations

impl Bitmap

pub const fn new() -> Self

Create a new empty bitmap

pub fn is_set(&self, field: u8) -> bool

Check if field is set using SIMD where available

pub fn set(&mut self, field: u8) -> Result<(), &'static str>

Set a field in the bitmap

pub fn clear(&mut self, field: u8) -> Result<(), &'static str>

Clear a field in the bitmap

pub fn is_empty(&self) -> bool

Check if bitmap is empty (SIMD optimized)

pub fn get_set_fields(&self) -> ([u8; 192], usize)

Get all set field numbers (returns array and count) Returns (fields_array, count) where count indicates how many fields are actually set

pub fn to_bytes(&self) -> ([u8; 24], usize)

Convert to bytes for transmission (returns array and length) Maximum size is 24 bytes (3 bitmaps)

pub fn from_bytes(bytes: &[u8]) -> Result<Self, &'static str>

Parse from bytes

pub fn from_hex(hex_str: &str) -> Result<Self, &'static str>

Parse from hex string

Trait Implementations

impl Clone for Bitmap

fn clone(&self) -> Bitmap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Bitmap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Bitmap

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Bitmap

fn eq(&self, other: &Bitmap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
