Struct DiskFileSource

Source

pub struct DiskFileSource;

Expand description

Default FileSource that reads directly from disk. Available for callers who want to register a source explicitly but keep disk-backed semantics.

Trait Implementations§

Source §

impl FileSource for DiskFileSource

Source §

fn read(&self, path: &str) -> Option<Vec<u8>>

Return the bytes at path, or None if the path is unknown. Errors during read are surfaced as None; this matches Lua’s existing “missing file” behaviour where fs.read raises a runtime error.
