Requires Nix Flakes.
|
||||
A template Rust project with fully functional and no-frills Nix support, as well as builtin VSCode configuration to get IDE support without doing anything (open in VSCode and accept the suggestions).
|
||||
|
||||
## Adapting this template
|
||||
|
||||
Change `name` in Cargo.toml and flake.nix. Also change `description` in flake.nix.
|
||||
|
||||
## Development (Flakes)
|
||||
|
||||
This repo uses [Flakes](https://nixos.wiki/wiki/Flakes) from the get-go, but compat is provided for traditional nix-shell/nix-build as well (see the section below).
|
||||
|
||||
```
|
||||
# dev shell
|
||||
# Dev shell
|
||||
nix develop
|
||||
|
||||
# or just run directly
|
||||
nix run
|
||||
|
||||
# or run via cargo
|
||||
nix develop -c cargo run
|
||||
|
||||
# build
|
||||
nix build
|
||||
```
|
||||
|
||||
## Development (Legacy Nix)
|
||||
|
||||
```
|
||||
# Dev shell
|
||||
nix-shell
|
||||
|
||||
# run via cargo
|
||||
nix-shell --run 'cargo run'
|
||||
|
||||
# build
|
||||
nix-build
|
||||
```
