Struct InputSpec 

pub struct InputSpec {
    pub shape: Vec<usize>,
    pub dshape: Vec<(DimName, usize)>,
    pub cameraadaptor: Option<String>,
    pub preprocessing: Option<Preprocessing>,
}

Input tensor specification.

Fields

shape: Vec<usize>

Input tensor shape in the model’s native layout (NCHW or NHWC).

dshape: Vec<(DimName, usize)>

Named dimensions ordered to match shape. Empty means the layout is unspecified and consumers must infer from the format.

cameraadaptor: Option<String>

Camera adaptor input format (rgb, rgba, bgr, bgra, grey, yuyv). Free-form string rather than an enum because new adaptor formats can appear without breaking parsing.

preprocessing: Option<Preprocessing>

Pre-processing the model expects: normalization, resize policy and letterbox geometry. None means the producer did not declare it; consumers fall back to validation.normalization / validation.preprocessing, then to unsigned + centred letterbox.

Implementations

impl InputSpec

pub fn channels(&self) -> Option<usize>

Channel count of the model input, when the layout can be resolved.

With a dshape, it is the size of the single axis not named batch, height or width. Without one, a rank-4 shape resolves only when exactly one of axis 1 (NCHW) and axis 3 (NHWC) holds 1 to 4 channels.

use edgefirst_decoder::schema::InputSpec;

let nchw: InputSpec = serde_json::from_str(r#"{"shape": [1, 3, 512, 512]}"#).unwrap();
assert_eq!(nchw.channels(), Some(3));
let ambiguous: InputSpec = serde_json::from_str(r#"{"shape": [1, 3, 4, 3]}"#).unwrap();
assert_eq!(ambiguous.channels(), None);
