# README

This README provides information about the `detect-rust-minimum-version` action.

## Description

The `detect-rust-minimum-version` action is a GitHub Action that detects the minimum required version of Rust for a Rust project. It scans the project's source code and analyzes the `Cargo.toml` file to determine the minimum required version.

## Usage

To use this action, you can include it in your workflow file as follows:

```yaml

name: Detect Rust Minimum Version

on:

    push:

        branches:

            - main

jobs:

    detect-rust-minimum-version:

        runs-on: ubuntu-latest

        steps:

            - name: Checkout repository

              uses: actions/checkout@v4

            - name: Detect Rust Minimum Version

              id: rust-version

              uses: derrix060/detect-rust-minimum-version@v2

              with:

                repos: repo/my-path1,repo/my-path2

                locked: true  # Enforce using Cargo.lock

                min: "1.78.0"  # Minimum Rust version to start searching from.

            

            - name: Print version

              run: echo "Minimum rust version is ${{ steps.rust-version.outputs.highest-msrv }}"

```

## Inputs

- `paths` (optional): A comma-separated list of relative paths to the directories or files that should be scanned for detecting the minimum required version of Rust. If not provided, the action will default to the current location.

- `locked` (optional): If true, passes --locked to cargo to enforce using Cargo.lock and prevent dependency re-resolution.

- `min` (optional): The minimum Rust version to start searching from. Useful when Cargo.lock uses v4 format (requires 1.78.0+).

## Outputs

- `highest-msrv`: The highest minimum Rust version required, based on a AND operation on all paths.  It basically means that it is the highest msrv for all the paths.
