Trait Implementations

impl FileLoader for RealFileLoader

fn file_exists(&self, path: &Path) -> bool

Query the existence of a file.

fn read_file(&self, path: &Path) -> Result<String>

Read the contents of a UTF-8 file into memory. This function must return a String because we normalize source files, which may require resizing.

fn read_binary_file(&self, path: &Path) -> Result<Lrc<[u8]>>

Read the contents of a potentially non-UTF-8 file into memory. We don’t normalize binary files, so we can start in an Lrc.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
