Fields

buffer: ResidentBufferRef<'a>

Backend-visible subband buffer.

component: ResidentComponentGeometry

Component geometry and sampling.

sample: ResidentSampleInfo

Coefficient precision and signedness.

color: ResidentColorModel

Color interpretation of the source image/component set.

level: u8

DWT decomposition level.

subband: ResidentDwtSubbandKind

Subband kind within the level.

width: u32

Native subband width in coefficients.

height: u32

Native subband height in coefficients.

row_pitch_bytes: usize

Byte stride between subband rows.

bytes_per_coefficient: usize

Bytes per coefficient in the resident buffer.

Implementations

impl<'a> ResidentDwtSubband<'a>

pub fn new( buffer: ResidentBufferRef<'a>, component: ResidentComponentGeometry, sample: ResidentSampleInfo, color: ResidentColorModel, layout: ResidentDwtSubbandLayout, ) -> Result<Self, ResidentHandoffError>

Build a resident DWT subband descriptor.

pub fn require_backend( self, backend: BackendKind, ) -> Result<Self, ResidentHandoffError>

Validate this descriptor is backed by the expected backend.

Trait Implementations

impl<'a> Clone for ResidentDwtSubband<'a>

fn clone(&self) -> ResidentDwtSubband<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for ResidentDwtSubband<'a>

impl<'a> Debug for ResidentDwtSubband<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for ResidentDwtSubband<'a>

impl<'a> PartialEq for ResidentDwtSubband<'a>

fn eq(&self, other: &ResidentDwtSubband<'a>) -> 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.
