Struct ModelSpec 

pub struct ModelSpec {
    pub name: String,
    pub source_url: String,
    pub sha256_hex: String,
    pub size_bytes: Option<u64>,
    pub license: Option<String>,
    pub source: Option<ManifestSource>,
}

One downloadable GGUF model. The fetch contract is one URL + expected SHA-256; anything more elaborate (registries, mirrors) belongs in the operator’s HTTP proxy or a wget step, not here.

Fields

name: String

Stable identifier, e.g. "gemma-4-e4b". Used as the manifest filename (<name>.json) and the lock-file basename.

source_url: String

Direct-download HTTPS endpoint. Must be https://. Empty string is permitted for CLI-only mode where the operator has pre-placed bytes at a manifest-defined blob path.

sha256_hex: String

Lowercase hex SHA-256 of the GGUF bytes. Required.

size_bytes: Option<u64>

Advisory total size for progress reporting + manifest. None = unknown (Content-Length missing); progress frames omit total_bytes and the manifest records the actually-downloaded size.

license: Option<String>

SPDX-style license id when known. Recorded in the manifest for cross-tool consumers; not consulted at runtime.

source: Option<ManifestSource>

Diagnostic provenance for the manifest. Optional — falls back to a derived shape from source_url if absent.
