Enum BacklightType 

#[non_exhaustive]
pub enum BacklightType {
    None,
    AcFluorescent,
    Dc,
    Unknown(u8),
}

Backlight type, decoded from Display Device Data Block (0x0C) byte 1 bits 5:4.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

No backlight, or not applicable (0).

AcFluorescent

AC fluorescent (CCFL) backlight (1).

Dc

DC-powered backlight (LED or other) (2).

Unknown(u8)

Reserved value (3).

Implementations

impl BacklightType

pub fn from_bits(bits: u8) -> Self

Decodes the backlight type from a 2-bit value (bits 5:4 of byte 1).

Trait Implementations

impl Clone for BacklightType

fn clone(&self) -> BacklightType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BacklightType

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

Formats the value using the given formatter.

impl PartialEq for BacklightType

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