CrateLite is a lightweight VS Code extension for editing Cargo.toml. It adds fast, focused completion for Rust dependencies without trying to be a full Cargo assistant.
Features
Crate name completion inside dependency sections
Latest version completion from a cached crate index
Feature completion inside features = []
Local index caching for quick suggestions after the first download
Usage
Open a Cargo.toml file and start typing in [dependencies]:
[dependencies]
ser
serde = "1"
tokio = { version = "1", features = ["rt-", "mac"] }
CrateLite will suggest:
matching crate names like serde
the latest known version for a crate
available feature names for inline dependency tables
Settings
cratelite.indexUrl: URL of the compressed crate index file
cratelite.maxSuggestions: maximum number of crate suggestions
cratelite.minTriggerLength: minimum typed characters before crate suggestions appear
cratelite.featureIndexBaseUrl: base URL for feature metadata lookups
Notes
The crate index is downloaded on first use and then cached locally.
Feature suggestions may require network access to fetch crate metadata.
