# Rust Bindings for nim-timer
|
|
|
|
## Purpose
|
|
|
|
This folder contains **auto-generated Rust bindings** (the `nimtimer` crate) for the `nim_timer` Nim library. It is generated from `../nim_timer.nim` and provides:
|
|
|
|
- `src/lib.rs`: Main library exposing high-level Rust types and the `NimTimerCtx` API
|
|
- `src/api.rs`: High-level async/sync wrapper around the FFI
|
|
- `src/ffi.rs`: Raw `extern "C"` declarations for the Nim library
|
|
- `src/types.rs`: Serializable Rust types matching the Nim FFI types
|
|
- `build.rs`: Build script that compiles the Nim library to `libnimtimer.dylib` (or `.so`/`.dll`)
|
|
- `Cargo.toml`: Package manifest with serde and serde_json dependencies
|
|
|
|
## How It's Generated
|
|
|
|
Generate or regenerate these bindings by running from the parent directory:
|
|
|
|
```sh
|
|
cd examples/nim_timer
|
|
nimble genbindings_rust
|
|
```
|
|
|
|
This command:
|
|
1. Invokes the Nim compiler with `-d:targetLang:rust` flag
|
|
2. Triggers `genBindings("examples/nim_timer/rust_bindings", "../nim_timer.nim")` in `nim_timer.nim`
|
|
3. Creates/updates the generated binding files
|
|
|
|
## Using as a Dependency
|
|
|
|
The `rust_client` example consumes this crate:
|
|
|
|
```toml
|
|
[dependencies]
|
|
nimtimer = { path = "../rust_bindings" }
|
|
```
|
|
|
|
## Do Not Edit
|
|
|
|
The generated files in this folder are overwritten each time `nimble genbindings_rust` runs. Any manual changes will be lost.
