Struct exr::block::lines::LineSlice

pub struct LineSlice<T> {
    pub location: LineIndex,
    pub value: T,
}

A single line of pixels. Use LineRef or LineRefMut for easier type names.

Fields

location: LineIndex

Where this line is located inside the image.

value: T

The raw bytes of the pixel line, either &[u8] or &mut [u8]. Must be re-interpreted as slice of f16, f32, or u32, according to the channel data type.

Implementations

impl<'s> LineSlice<&'s mut [u8]>

pub fn write_samples_from_slice<T: Data>(self, slice: &[T]) -> UnitResult

Writes the samples (f16, f32, u32 values) into this line value reference. Use write_samples if there is not slice available.

pub fn write_samples<T: Data>( self, get_sample: impl FnMut(usize) -> T, ) -> UnitResult

Iterate over all samples in this line, from left to right. The supplied get_line function returns the sample value for a given sample index within the line, which starts at zero for each individual line. Use write_samples_from_slice if you already have a slice of samples.

impl LineSlice<&[u8]>

pub fn read_samples_into_slice<T: Data>(self, slice: &mut [T]) -> UnitResult

Read the samples (f16, f32, u32 values) from this line value reference. Use read_samples if there is not slice available.

pub fn read_samples<T: Data>(&self) -> impl Iterator<Item = Result<T>> + '_

Iterate over all samples in this line, from left to right. Use read_sample_into_slice if you already have a slice of samples.

Trait Implementations

impl<T: Clone> Clone for LineSlice<T>

fn clone(&self) -> LineSlice<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for LineSlice<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for LineSlice<T>

fn eq(&self, other: &LineSlice<T>) -> 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.
