Struct HintMask

struct HintMask {
    mask: [u8; 12],
    is_valid: bool,
}

Bitmask that specifies which hints are currently active.

“Each bit of the mask, starting with the most-significant bit of the first byte, represents the corresponding hint zone in the order in which the hints were declared at the beginning of the charstring.”

Implementations

impl HintMask

fn new(bytes: &[u8]) -> Option<Self>

fn all() -> Self

fn clear(&mut self, bit: usize)

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

Trait Implementations

impl Clone for HintMask

fn clone(&self) -> HintMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for HintMask

fn default() -> HintMask

Returns the “default value” for a type.

impl PartialEq for HintMask

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

impl Copy for HintMask
