Struct Description 

pub struct Description {
    pub width: u32,
    pub height: u32,
    pub descriptor: PixelDescriptor,
    pub color_context: Option<Arc<ColorContext>>,
    pub exact_depth: Option<ExactDepth>,
}

Fixed sample declaration for this operation. Color conversion is not implicit.

Fields

width: u32

Width in samples.

height: u32

Total rows.

descriptor: PixelDescriptor

Complete sample descriptor accepted by the configured encoder.

color_context: Option<Arc<ColorContext>>

Original color context carried on every source and encoder row view.

exact_depth: Option<ExactDepth>

Optional assertion about current canonical samples, checked before push. Some is strict: unsupported layouts refuse before startup, including full-storage CMYK claims. None does not restrict sample depth. It does not prove the encoder preserves samples or bound native memory.

Implementations

impl Description

pub const fn new(width: u32, height: u32, descriptor: PixelDescriptor) -> Self

Construct a declaration; execution checks dimensions and size arithmetic.

pub fn with_color_context(self, context: Arc<ColorContext>) -> Self

Attach the actual sample context without changing the descriptor.

pub const fn with_exact_depth(self, exact: ExactDepth) -> Self

State a sample-grid claim; execution verifies each active row before push. Supported layouts follow EncodeDeclaration::exact_depth. A claim changes admission: it must be verifiable even if the encoder ignores it.

Trait Implementations

impl Clone for Description

fn clone(&self) -> Description

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Description

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

Formats the value using the given formatter.

impl Eq for Description

impl PartialEq for Description

fn eq(&self, other: &Description) -> bool

Equality operator ==.

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

Inequality operator !=.
