Struct FeatureMap 

pub struct FeatureMap {
    pub data: Vec<f32>,
    pub channels: usize,
    pub height: usize,
    pub width: usize,
}

A single-level feature map in CHW layout.

data is stored as [channels, height, width] in row-major order.

Fields

data: Vec<f32>

Flat data buffer: [channels × height × width].

channels: usize

Number of feature channels.

height: usize

Spatial height (rows).

width: usize

Spatial width (columns).

Implementations

impl FeatureMap

pub fn new( data: Vec<f32>, channels: usize, height: usize, width: usize, ) -> VisionResult<Self>

Construct a FeatureMap, validating that the data length matches the shape.

Errors

DimensionMismatch if data.len() != channels * height * width.

pub fn at(&self, c: usize, h_idx: usize, w_idx: usize) -> f32

Sample the value at channel c, row h_idx, column w_idx.

Panics in debug builds if any index is out of range (same contract as direct slice indexing — callers are responsible for bounds checking).

Trait Implementations

impl Clone for FeatureMap

fn clone(&self) -> FeatureMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureMap

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

Formats the value using the given formatter.
