Struct Catalog 

pub struct Catalog {
    pub models: Vec<CatalogModel>,
}

A collection of locally-available models.

Fields

models: Vec<CatalogModel>

Implementations

impl Catalog

pub fn seed() -> Self

The built-in catalog: every model the worker ships seeded with.

pub fn from_json(json: &str) -> Result<Self>

Parse a catalog from a JSON string.

pub fn to_json(&self) -> Result<String>

Serialise to pretty JSON.

pub fn load_or_seed(path: &Path) -> Result<Self>

Load the catalog from path. If the file does not exist it is seeded with the built-in defaults and written to path.

pub fn save(&self, path: &Path) -> Result<()>

Write the catalog to path (creating parent dirs).

pub fn get(&self, id: &str) -> Option<&CatalogModel>

Look up a model by id.

pub fn list(&self) -> &[CatalogModel]

All catalog entries.

pub fn upsert(&mut self, model: CatalogModel)

Insert a model, replacing any existing entry with the same id.

pub fn remove(&mut self, id: &str) -> bool

Remove a model by id. Returns whether it existed.

pub fn default_image_model(&self) -> Option<&CatalogModel>

The first enabled image model — used when a request names no model.
