Language Server Index Format (LSIF) is a standard format for language servers or other programming tools to dump their knowledge about a code workspace (article). lsif-rust is an attempt to implement such a tool for Rust since none exists for the language as listed on lsif.dev.
sh
cargo install lsif-rust
Run the command in the same directory as Cargo.toml. Requires nightly Rust (for -Z save-analysis).
```sh lsif-rust 0.0.1 LSIF Indexer for Rust
USAGE: lsif-rust [OPTIONS]
FLAGS: -h, --help Prints help information -V, --version Prints version information
OPTIONS:
