Struct rsass::input::CargoLoader

pub struct CargoLoader { /* private fields */ }

A Loader for when calling rsass from a build.rs script.

This is very similar to a FsLoader, but has a for_crate constructor that uses the CARGO_MANIFEST_DIR environment variable instead of the current working directory, and it prints cargo:rerun-if-changed messages for each path that it loads.

Implementations

impl CargoLoader

pub fn for_crate() -> Result<Self, LoadError>

Create a new FsFileContext.

Files will be resolved from the directory containing the manifest of your package. This assumes the program is called by cargo, so the CARGO_MANIFEST_DIR environment variable is set.

pub fn push_path(&mut self, path: &Path) -> Result<(), LoadError>

Add a path to search for files.

The path can be relative to the crate manifest directory, or absolute.

pub fn for_path(path: &Path) -> Result<(Self, SourceFile), LoadError>

Create a Loader and a SourceFile from a given Path.

The path can be relative to the crate manifest directory, or absolute.
