Struct rsass::FileContext

pub struct FileContext { /* fields omitted */ }

A file context specifies where to find files to load.

When opening an included file, an extended file context is created, to find further included files relative to the file they are inlcuded from.

Example

use rsass::FileContext;
use std::path::PathBuf;

let base = FileContext::new();
let (base, file1) =
    base.file(&PathBuf::from("some").join("dir").join("file.scss"));
// base is now a relative to file1, usefull to open files
// by paths mentioned in file1.
let (base, file2) = base.file("some/other.scss".as_ref());
assert_eq!(file1, PathBuf::from("some").join("dir").join("file.scss"));
assert_eq!(file2, PathBuf::from("some").join("dir").join("some/other.scss"));
