Implementations

impl PixelFormat

pub fn is_compressed(&self) -> bool

判断是否为压缩格式 (JPEG, H264)

pub fn is_bayer(&self) -> bool

判断是否为 Bayer 原始格式 (需要 Demosaic)

pub fn bpp_estimate(&self) -> u32

估算每像素比特数 (Bits Per Pixel)，用于计算带宽

Trait Implementations

impl Clone for PixelFormat

fn clone(&self) -> PixelFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelFormat

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

Formats the value using the given formatter.

impl From<FourCC> for PixelFormat

fn from(cc: FourCC) -> Self

Converts to this type from the input type.

impl From<u32> for PixelFormat

fn from(val: u32) -> Self

Converts to this type from the input type.

impl PartialEq<FourCC> for PixelFormat

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

impl PartialEq<PixelFormat> for FourCC

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