Struct ModelSpec 

#[non_exhaustive]
pub struct ModelSpec {
    pub name: &'static str,
    pub file: &'static str,
    pub sha256: &'static str,
    pub install_command: &'static str,
}

What a model package must provide.

Declared as a const by each model feature; the file is resolved as <model dir>/<name>/<file> and verified against sha256 before loading.

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.

name: &'static str

Package directory inside the model dir, e.g. "layout-heron-ep03".

file: &'static str

File name inside the package dir, e.g. "heron_ep03.onnx".

sha256: &'static str

Lowercase hex SHA-256 the file must match before it is loaded.

install_command: &'static str

Shown verbatim in MODEL_NOT_AVAILABLE: where to get the package.

Implementations

impl ModelSpec

pub const fn new( name: &'static str, file: &'static str, sha256: &'static str, install_command: &'static str, ) -> Self

Declare a model package. const so model features can hold it as a const rather than building it per call.
