Struct DmaBufFormat 

pub struct DmaBufFormat {
    pub fourcc: u32,
    pub modifier_hi: u32,
    pub modifier_lo: u32,
}

DMA-BUF format descriptor (fourcc + modifier pair).

Each supported format is advertised as a (fourcc, modifier) combination. The modifier describes the GPU-specific memory layout (e.g., linear, tiled). A single fourcc may appear with multiple modifiers.

Fields

fourcc: u32

DRM fourcc format code

modifier_hi: u32

Upper 32 bits of the 64-bit modifier

modifier_lo: u32

Lower 32 bits of the 64-bit modifier

Implementations

impl DmaBufFormat

pub fn new(fourcc: u32, modifier: u64) -> Self

Create a new format descriptor.

pub fn modifier(&self) -> u64

Reconstruct the full 64-bit modifier.

pub fn is_linear(&self) -> bool

Check whether this format uses the linear modifier.

Trait Implementations

impl Clone for DmaBufFormat

fn clone(&self) -> DmaBufFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DmaBufFormat

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

Formats the value using the given formatter.

impl PartialEq for DmaBufFormat

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