Struct LumaFormat 

pub struct LumaFormat;

A Zero-Size-Type that contains the definition to convert a given image stream to an Luma8(Grayscale 8-bit) in the Buffer’s .decode_image()

use image::{ImageBuffer, Luma};
let image: ImageBuffer<Luma<u8>, Vec<u8>> = buffer.to_image::<LumaFormat>();

Trait Implementations

impl Clone for LumaFormat

fn clone(&self) -> LumaFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LumaFormat

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

Formats the value using the given formatter.

impl Default for LumaFormat

fn default() -> LumaFormat

Returns the “default value” for a type.

impl FormatDecoder for LumaFormat

const FORMATS: &'static [FrameFormat]

type Output = Luma<u8>

fn write_output( fcc: FrameFormat, resolution: Resolution, data: &[u8], ) -> Result<Vec<u8>, NokhwaError>

Allocates and returns a Vec

fn write_output_buffer( fcc: FrameFormat, _resolution: Resolution, data: &[u8], dest: &mut [u8], ) -> Result<(), NokhwaError>

Writes to a user provided buffer.

impl Hash for LumaFormat

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

where __H: Hasher,

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 Ord for LumaFormat

fn cmp(&self, other: &LumaFormat) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LumaFormat

fn eq(&self, other: &LumaFormat) -> 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 PartialOrd for LumaFormat

fn partial_cmp(&self, other: &LumaFormat) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
