Struct DisplayGamma 

pub struct DisplayGamma(/* private fields */);

Display gamma, decoded from EDID base block byte 0x17.

Gamma is encoded as (value * 100) - 100, so a stored byte of 120 represents gamma 2.20. A byte value of 0xFF means gamma is undefined; use None on DisplayCapabilities in that case.

Implementations

impl DisplayGamma

pub fn from_edid_byte(byte: u8) -> Option<DisplayGamma>

Decodes EDID byte 0x17 into a DisplayGamma.

Returns None if the byte is 0xFF (gamma not specified).

pub fn raw(&self) -> u8

Returns the raw encoded byte.

pub fn value(&self) -> f32

Returns the gamma value as a floating-point number (e.g. 2.20).

Trait Implementations

impl Clone for DisplayGamma

fn clone(&self) -> DisplayGamma

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayGamma

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

Formats the value using the given formatter.

impl PartialEq for DisplayGamma

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