Tuple Fields

0: c_uint

Implementations

impl SDL_ChromaLocation

pub const SDL_CHROMA_LOCATION_NONE: SDL_ChromaLocation

< RGB, no chroma sampling

pub const SDL_CHROMA_LOCATION_LEFT: SDL_ChromaLocation

< In MPEG-2, MPEG-4, and AVC, Cb and Cr are taken on midpoint of the left-edge of the 2x2 square. In other words, they have the same horizontal location as the top-left pixel, but is shifted one-half pixel down vertically.

pub const SDL_CHROMA_LOCATION_CENTER: SDL_ChromaLocation

< In JPEG/JFIF, H.261, and MPEG-1, Cb and Cr are taken at the center of the 2x2 square. In other words, they are offset one-half pixel to the right and one-half pixel down compared to the top-left pixel.

pub const SDL_CHROMA_LOCATION_TOPLEFT: SDL_ChromaLocation

< In HEVC for BT.2020 and BT.2100 content (in particular on Blu-rays), Cb and Cr are sampled at the same location as the group’s top-left Y pixel (“co-sited”, “co-located”).

Trait Implementations

impl Clone for SDL_ChromaLocation

fn clone(&self) -> SDL_ChromaLocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_ChromaLocation

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

Formats the value using the given formatter.

impl Hash for SDL_ChromaLocation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SDL_ChromaLocation

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