Console4852 (talk | contribs) Remove Neovim Completion Section. This section references racer, which hasn't been relevant for rust autocomplete in years now (the last commit on the project was 2 years ago). It's also not a valid, working snippet - nor does it configure neovim in a way you'd expect. |

== Installating with bindgen support == | |||
By default crates using <code>bindgen</code> will not compile. To add bindegen support add the <code>rustPlatform.bindegenHook</code> to your <code>nativeBuildInputs</code>. | |||
Here's an example <code>shell.nix</code>: | |||
<syntaxHighlight lang="nix"> | |||
{ pkgs ? import <nixpkgs> {} }: | |||
pkgs.mkShell { | |||
nativeBuildInputs = [ | |||
pkgs.cargo | |||
pkgs.rustc | |||
pkgs.rustPlatform.bindgenHook | |||
# optional: add pkg-config support | |||
pkgs.pkg-config | |||
]; | |||
buildInputs = [ | |||
# add desired native packages | |||
# ... | |||
]; | |||
# ... | |||
} | |||
</syntaxHighlight> | |||
This also works, when compiling rust crates: | |||
<syntaxHighlight lang="nix"> | |||
{ | |||
rustPlatform, | |||
pkg-config, | |||
... | |||
}: | |||
rustPlatform.buildRustPackage { | |||
# ... | |||
nativeBuildInputs = [ | |||
rustPlatform.bindgenHook | |||
pkg-config | |||
]; | |||
buildInputs = [ | |||
# add desired native packages | |||
# ... | |||
]; | |||
} | } | ||

The important part is that this also works with complex setups using bindgen and precompiled C libraries. To add a new C library in the search path of bindgen and rustc edit the variables <code>BINDGEN_EXTRA_CLANG_ARGS</code> and <code>RUSTFLAGS</code> | The important part is that this also works with complex setups using bindgen and precompiled C libraries.
