Enum ScanDirection 

#[non_exhaustive]
pub enum ScanDirection {
    NotDefined,
    Normal,
    Reversed,
    Reserved,
}

Scan direction of the fast (horizontal) scan relative to H-sync, decoded from Display Device Data Block (0x0C) byte 7 bits 7:6.

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.

NotDefined

Scan direction not defined (0).

Normal

Fast scan follows the H-sync direction; slow scan follows V-sync direction (1).

Reversed

Fast scan direction is opposite to H-sync; slow scan opposite to V-sync (2).

Reserved

Reserved value (3).

Implementations

impl ScanDirection

pub fn from_bits(bits: u8) -> Self

Decodes the scan direction from a 2-bit value (bits 7:6 of byte 7).

Trait Implementations

impl Clone for ScanDirection

fn clone(&self) -> ScanDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScanDirection

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

Formats the value using the given formatter.

impl PartialEq for ScanDirection

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