ModelSource class abstract

The acquisition seam: where model weights come from and how they're verified. A provider concern (like FlagsSource), not a bridge onto juice_network — so HTTP-with-resume, a CDN client, or a bundled-asset copy are all just implementations.

Contract: fetch MUST verify model.sha256 against the downloaded bytes and, on mismatch, delete the file and throw ModelChecksumException — unverified weights are never reported present.

Constructors

ModelSource()

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

delete(LlmModel model, String destinationPath) → Future<void>

Remove the weights at destinationPath (free disk).

fetch(LlmModel model, String destinationPath) → Stream<ModelFetchProgress>

Acquire model to destinationPath, streaming progress. Resumable implementations pick up a partial file; all implementations verify the checksum before the terminal done event.

isPresent(LlmModel model, String destinationPath) → Future<bool>

Whether verified weights already sit at destinationPath.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
