Struct ModelSpec 

pub struct ModelSpec {
    pub variant: &'static str,
    pub kind_label: &'static str,
    pub default_subdir: &'static str,
    pub required_files: &'static [&'static str],
    pub env_var: &'static str,
    pub install_command: &'static str,
    pub model_flag: &'static str,
    pub source: ModelSource,
}

Fully describes a model variant’s storage, install transport, and CLI surface. Static lifetime: every field is &'static str (or &'static [&'static str]) so ModelSpec is Copy and 'static.

Fields

variant: &'static str

CLI-facing variant identifier: "whisper-tiny.en" or "speaker-wespeaker-en". Matches the --variant value the user passes to voice install-model.

kind_label: &'static str

Human label used in error messages: "Whisper" or "Speaker".

default_subdir: &'static str

Subdirectory beneath ~/.omni-dev/voice/models/ where this model’s files live.

required_files: &'static [&'static str]

Files that must exist in the install directory for the model to be considered installed.

env_var: &'static str

Environment-variable override for the install directory.

install_command: &'static str

Recommended install-model invocation, used verbatim in the ensure_model_present error hint.

model_flag: &'static str

CLI flag that overrides the model path on consumer commands, e.g. "--model" (Whisper) or "--speaker-model" (wespeaker).

source: ModelSource

How to fetch the bytes.

Implementations

impl ModelSpec

pub fn default_dir(&self) -> Option<PathBuf>

Default install directory: ~/.omni-dev/voice/models/<default_subdir>/.

None when the user’s home directory cannot be located — same failure mode as dirs::home_dir().

pub fn resolve_dir(&self, override_path: Option<&Path>) -> Result<PathBuf>

Resolves the install directory for this spec.

Priority: override_path → env var → default. The returned path is not validated for existence; pair with Self::ensure_present for fail-fast.

pub fn required_files_in(&self, dir: &Path) -> Vec<PathBuf>

Returns the absolute path of each required file inside dir.

pub fn ensure_present(&self, dir: &Path) -> Result<()>

Verifies that dir contains every file in self.required_files.

On failure, returns the install hint shaped for this spec (the install_command / model_flag baked into the spec).

Trait Implementations

impl Clone for ModelSpec

fn clone(&self) -> ModelSpec

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

Performs copy-assignment from source.

impl Debug for ModelSpec

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

Formats the value using the given formatter.
