Enum CvtAlgorithm 

#[non_exhaustive]
pub enum CvtAlgorithm {
    Cvt,
    CvtRb,
    CvtR2,
    Reserved(u8),
}

CVT formula selector for DisplayID 2.x Type IX (0x24) and Type V (0x11) Formula-Based Timings.

Decoded from byte 0 bits 2:0. Identifies which CVT variant the consumer should use to derive blanking parameters and pixel clock from the (width, height, refresh_rate) triple stored on VideoMode. Codes 3–7 are reserved by the DisplayID 2.x spec; unknown encodings are surfaced as CvtAlgorithm::Reserved so a future spec value does not block decoding of the rest of the descriptor.

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.

Cvt

Standard CVT (no reduced blanking) (encoding 0).

CvtRb

CVT-RB v1 (encoding 1).

CvtR2

CVT-R2 / CVT-RB v2 (encoding 2).

Reserved(u8)

Spec-reserved encoding (3–7) preserved verbatim so unknown values do not block decoding of the rest of the descriptor.

Implementations

impl CvtAlgorithm

pub const fn from_bits(b: u8) -> Self

Decodes the 3-bit CVT algorithm field (Type V/IX descriptor byte 0 bits 2:0). Upper bits of the input are ignored.
