Struct Preprocessing 

#[non_exhaustive]
pub struct Preprocessing {
    pub normalization: Option<Normalization>,
    pub resize: Option<ResizeMode>,
    pub interpolation: Option<Interpolation>,
    pub letterbox: Option<Letterbox>,
}

Input pre-processing declared by the model producer.

Every field is optional; an absent field means “not declared” rather than a specific default, so consumers can apply their own fallback.

use edgefirst_decoder::schema::{InputSpec, NormalizationPreset, Normalization};

let input: InputSpec = serde_json::from_str(r#"{
  "shape": [1, 3, 512, 512],
  "preprocessing": {
    "normalization": "imagenet",
    "resize": "letterbox",
    "letterbox": {"placement": "top_left", "pad": [0, 0, 0], "pad_space": "normalized"}
  }
}"#).unwrap();
let pre = input.preprocessing.unwrap();
assert_eq!(pre.normalization, Some(Normalization::Preset(NormalizationPreset::Imagenet)));

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.

normalization: Option<Normalization>

Per-channel normalization applied to 0–255 input values.

resize: Option<ResizeMode>

How a frame is fitted to the fixed model input.

interpolation: Option<Interpolation>

Resampling filter of the reference pipeline. Informational: a runtime may use a different filter and should report the deviation.

letterbox: Option<Letterbox>

Letterbox geometry; meaningful when resize is letterbox.

Trait Implementations

impl Clone for Preprocessing

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Preprocessing

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

Formats the value using the given formatter.

impl Default for Preprocessing

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Preprocessing

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Preprocessing

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Preprocessing

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
