Crate cargo_nightly 

Cargo subcommand to forward commands to the nightly toolchain.

This extension enables nightly toolchain usage in cargo aliases by providing a cargo-nightly subcommand that forwards all arguments to cargo +nightly <args>.

Why it exists

Cargo aliases in .cargo/config.toml cannot directly use +nightly syntax because cargo aliases can only invoke cargo subcommands, not external commands or toolchain selectors. This plugin provides a cargo-nightly subcommand that forwards all arguments to cargo +nightly <args>, making it possible to use nightly toolchain commands through cargo aliases.

Usage

Once installed, you can use it directly:

cargo nightly clippy
cargo nightly check

Or through aliases in .cargo/config.toml:

[alias]
clippy2 = "nightly clippy"
check2 = "nightly clippy"

Example

# .cargo/config.toml
[alias]
clippy2 = "nightly clippy"
check2 = "nightly clippy"
clippy-all = "nightly clippy --workspace --all-targets --all-features -- -D warnings"

Then use the aliases:

cargo clippy2
cargo check2
cargo clippy-all
