Enum ContrastLevel 

pub enum ContrastLevel {
    AaNormal,
    AaLarge,
    AaaNormal,
    AaaLarge,
}

WCAG 2.1 conformance level for contrast checking.

Variants

AaNormal

AA for normal text (≥ 4.5:1).

AaLarge

AA for large text (≥ 3.0:1).

AaaNormal

AAA for normal text (≥ 7.0:1).

AaaLarge

AAA for large text (≥ 4.5:1).

Implementations

impl ContrastLevel

pub fn threshold(self) -> f64

Minimum contrast ratio required for this level.

pub fn passes(self, ratio: f64) -> bool

Whether the given ratio meets this conformance level.

Trait Implementations

impl Clone for ContrastLevel

fn clone(&self) -> ContrastLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContrastLevel

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

Formats the value using the given formatter.

impl Hash for ContrastLevel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ContrastLevel

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