Enum ContrastLevel 

pub enum ContrastLevel {
    Fail,
    AALarge,
    AA,
    AAALarge,
    AAA,
}

Variants

Fail

Fails WCAG requirements (ratio < 3.0)

AALarge

WCAG AA for large text (ratio >= 3.0)

AA

WCAG AA for normal text (ratio >= 4.5)

AAALarge

WCAG AAA for large text (ratio >= 4.5)

AAA

WCAG AAA for normal text (ratio >= 7.0)

Implementations

impl ContrastLevel

pub fn from_ratio(ratio: f64) -> Self

Determine WCAG compliance level from a contrast ratio

pub fn meets(self, required: ContrastLevel) -> bool

Check if this level meets the specified minimum requirement

pub fn name(self) -> &'static str

Display name for this compliance 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 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.
