# cargo-msrv Plugin

Cargo subcommand to determine the Minimum Supported Rust Version (MSRV). Verify Rust version compatibility for crates and projects.

## Commands

### MSRV Detection
- `cargo-msrv rust find` — Find the minimum supported Rust version

### Utility
- `cargo-msrv _ _` — Passthrough to cargo msrv CLI

## Usage Examples
- "Find MSRV for this project"
- "Determine minimum Rust version"
- "Verify Rust compatibility"
- "Check MSRV for crate"

## Installation

```bash
cargo install cargo-msrv
```

## Examples

```bash
# Find MSRV for current project
cargo msrv

# Search with version range
cargo msrv --min 1.56.0 --max 1.70.0

# Verify specific version
cargo msrv --verify 1.60.0

# JSON output
cargo msrv --output-format json

# Any cargo msrv command with passthrough
cargo msrv --min 1.50.0
cargo msrv --bisect
cargo msrv --release
```
