Struct InterpolateDescriptor 

#[non_exhaustive]
pub struct InterpolateDescriptor {
    pub n: i32,
    pub c: i32,
    pub ih: i32,
    pub iw: i32,
    pub oh: i32,
    pub ow: i32,
    pub mode: InterpolateMode,
    pub element: ElementKind,
    pub align_corners: bool,
    pub scale_h: Option<f64>,
    pub scale_w: Option<f64>,
}

Descriptor for an interpolate op.

#[non_exhaustive] (Phase 32) — Phase 21 added align_corners / scale_h / scale_w; future modes may add more fields. Use Self::new + the with_* setters from downstream code.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

n: i32

Batch.

c: i32

Channels.

ih: i32

Input height.

iw: i32

Input width.

oh: i32

Output height.

ow: i32

Output width.

mode: InterpolateMode

Interpolation mode.

element: ElementKind

Value element type. Must match T::KIND.

align_corners: bool

Coordinate alignment mode. false matches PyTorch F.interpolate new-code default; true matches nn.Upsample(align_corners=True).

scale_h: Option<f64>

Per-axis SCALE override for height (output_size / input_size). None derives the scale from (ih, oh); Some(s) overrides and the kernel uses 1.0 / s per output coordinate. Matches PyTorch’s scale_factor semantics.

scale_w: Option<f64>

Per-axis SCALE override for width (output_size / input_size). None derives the scale from (iw, ow); Some(s) overrides and the kernel uses 1.0 / s per output coordinate. Matches PyTorch’s scale_factor semantics.

Implementations

impl InterpolateDescriptor

pub fn new( n: i32, c: i32, ih: i32, iw: i32, oh: i32, ow: i32, mode: InterpolateMode, element: ElementKind, ) -> Self

Build a descriptor with align_corners = false (PyTorch F.interpolate new-code default) and scale_h / scale_w = None (derive scale from (ih, oh) / (iw, ow)). Chain with the with_* setters to override.

pub fn with_align_corners(self, align_corners: bool) -> Self

Override align_corners. Default false.

pub fn with_scale_h(self, scale_h: Option<f64>) -> Self

Override the per-axis SCALE for height. Default None (derive from (ih, oh)).

pub fn with_scale_w(self, scale_w: Option<f64>) -> Self

Override the per-axis SCALE for width. Default None (derive from (iw, ow)).
