Struct ModelOverrides 

#[non_exhaustive]
pub struct ModelOverrides {
    pub task: Option<ModelTask>,
    pub normalize: Option<NormalizeOverride>,
    pub resize: Option<ResizeOverride>,
    pub decode: Option<DecodeMode>,
    pub labels: Option<Vec<String>>,
}

Values that replace what discovery found, applied after every source and recorded as ConfigSource::Override.

use edgefirst_decoder::model_config::{ModelOverrides, ResizeOverride};
use edgefirst_tensor::LetterboxPlacement;

let mut o = ModelOverrides::default();
o.set("resize", "letterbox-topleft").unwrap();
o.set("labels", "background, person").unwrap();
assert_eq!(o.resize, Some(ResizeOverride::Letterbox(Some(LetterboxPlacement::TopLeft))));
assert_eq!(o.labels.as_deref(), Some(&["background".to_string(), "person".to_string()][..]));
assert!(o.set("resize", "fill").is_err());

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.

task: Option<ModelTask>

What the outputs decode to.

normalize: Option<NormalizeOverride>

Input normalization.

resize: Option<ResizeOverride>

Resize mode.

decode: Option<DecodeMode>

Semantic decode mode.

labels: Option<Vec<String>>

Class names, in channel order. Resolution checks their number only against a class count the model’s outputs state; end-to-end detections and class maps state none, so any number is accepted there and the caller checks it.

Implementations

impl ModelOverrides

pub fn new() -> Self

No overrides.

pub fn is_empty(&self) -> bool

Whether no override is set.

pub fn set(&mut self, key: &str, value: &str) -> Result<(), ModelConfigError>

Sets the override named key (task, normalize, resize, decode or labels) from its string form. labels is a comma-separated list of non-empty names.

Errors

ModelConfigError::Override for an unknown key or a value outside the key’s grammar.
