`perSystem.nci.crates`

Crate configurations

Type: lazy attribute set of (submodule)

Default: { }

Example:

{
  my-crate = {
    export = true;
    overrides = {/* stuff */};
  };
}

Declared by:

`perSystem.nci.crates.<name>.depsOverrides`

Overrides to apply to this crate’s dependency derivations (see dream2nix Rust docs for crane) Any overrides here that have the same name as project-wide overrides will take precedence over project-wide ones.

Type: attribute set of (attribute set)

Default: { }

Example:

{
  add-env = {TEST_ENV = 1;};
  add-inputs.overrideAttrs = old: {
    buildInputs = (old.buildInputs or []) ++ [pkgs.hello];
  };
}

Declared by:

`perSystem.nci.crates.<name>.export`

Whether to export this all of this crate’s outputs (if set will override project-wide setting)

Type: null or boolean

Default: null

Example: true

Declared by:

`perSystem.nci.crates.<name>.overrides`

Overrides to apply to this crate (see dream2nix Rust docs for crane) Any overrides here that have the same name as project-wide overrides will take precedence over project-wide ones.

Type: attribute set of (attribute set)

Default: { }

Example:

{
  add-env = {TEST_ENV = 1;};
  add-inputs.overrideAttrs = old: {
    buildInputs = (old.buildInputs or []) ++ [pkgs.hello];
  };
}

Declared by:

`perSystem.nci.crates.<name>.profiles`

Profiles to generate packages for this crate (if set will override project-wide setting)

Type: null or (attribute set of (submodule))

Default: null

Example:

{
  dev = {};
  release.runTests = true;
  custom-profile.features = ["some" "features"];
}

Declared by:

`perSystem.nci.crates.<name>.profiles.<name>.features`

Features to enable for this profile. Set to ‘null’ to enable default features only (this is the default). If set to a list of features then ‘–no-default-features’ will be passed to Cargo. If you want to also enable default features you can add ‘default’ feature to the list of features.

Type: null or (list of string)

Default: "[\"default\"]"

Example:

["tracing" "publish"]

Declared by:

`perSystem.nci.crates.<name>.profiles.<name>.runTests`

Whether to run tests for this profile

Type: boolean

Default: false

Example: true

Declared by:

`perSystem.nci.crates.<name>.renameTo`

What to rename this crate’s outputs to in nix flake show

Type: null or string

Default: null

Declared by:

`perSystem.nci.crates.<name>.runtimeLibs`

Runtime libraries that will be:

patched into the binary at build time,
present in LD_LIBRARY_PATH environment variable in development shell.

Note that when it’s patched in at build time, a separate derivation will be created that “wraps” the original derivation to not cause the whole crate to recompile when you only change runtimeLibs. The original derivation can be accessed via .passthru.unwrapped attribute.

Type: list of package

Default: [ ]

Example:

[pkgs.alsa-lib pkgs.libxkbcommon]

Type: package (read only)

Declared by:

nix-cargo-integration/src/modules/output.nix

`perSystem.nci.projects`

Type: lazy attribute set of (submodule)

Default: { }
