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) -> BacklightType
