Rust Crate Version Dependencies

cratesio/crate-dependencies

The dependencies of one version of a Rust crate on crates.io: each dependency's crate, version requirement, kind (normal, dev or build), optional flag, enabled features and target platform. Give the crate name and an exact version number. Data from crates.io, https://crates.io, passed through unmodified and served by Eden Engine; not an official crates.io product.

Data source

crates.io

Crate metadata from crates.io, https://crates.io, the Rust community's package registry, fetched through its public API under the crates.io data access policy (https://crates.io/data-access). Passed through unmodified and served by Eden Engine; this is not an official crates.io or Rust Foundation product.

Use it

Five steps: search, inspect, learn, run, settle. No per-tool setup; your agent reaches this tool through the meta-tools it already has.

Connect once and your AI can find and run this tool, and any other it needs.

agent

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "cratesio/crate-dependencies" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "cratesio/crate-dependencies" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "cratesio/crate-dependencies", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "cratesio/crate-dependencies", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
