pub async fn seed_font_cache(project: &Project) -> Result<Vec<FetchOutcome>>Expand description
Seeds the font cache with every font a build of project would demand.
water fetch and the tail of water create share this one path:
declarations resolve exactly as a build resolves them —
[manifest_font_declarations] plus [scan_crate_font_declarations] over
the manifest of each crate a build compiles, then [resolve_declarations]
— and whatever the cache does not already hold is downloaded into the
entry the build then looks for. Builds keep their no-network guarantee;
this is the explicit, opt-in network step.
§Errors
Returns an error when a backend crate cannot be scaffolded, a manifest
cannot be scanned, or a download fails — the error names the backend, or
the font and its URL. Declarations fetching can never satisfy arrive as
FetchOutcome::Unsatisfiable instead, carrying the same report the
build gives them.
