Struct FlagValue 

pub struct FlagValue {
    pub value: u64,
    pub names: &'static [&'static str],
}

Named bit flags for protocol fields.

Stores a flag value along with names for each bit position.

Fields

value: u64

The raw flag bits.

names: &'static [&'static str]

Flag names indexed by bit position (LSB = index 0).

Implementations

impl FlagValue

pub fn new(value: u64, names: &'static [&'static str]) -> Self

pub fn has(&self, bit: usize) -> bool

Check if a specific flag bit is set.

pub fn has_named(&self, name: &str) -> Option<bool>

Check if a named flag is set. Returns None if name not found.

pub fn set(&mut self, bit: usize)

Set a specific flag bit.

pub fn clear(&mut self, bit: usize)

Clear a specific flag bit.

pub fn set_flags(&self) -> Vec<&'static str>

Get the list of set flag names.

Trait Implementations

impl Clone for FlagValue

fn clone(&self) -> FlagValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlagValue

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

Formats the value using the given formatter.

impl Display for FlagValue

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

Formats the value using the given formatter.

impl PartialEq for FlagValue

fn eq(&self, other: &Self) -> 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.
