Trait protox::file::FileResolver

pub trait FileResolver {
    // Required method
    fn open_file(&self, name: &str) -> Result<File, Error>;

    // Provided method
    fn resolve_path(&self, _path: &Path) -> Option<String> { ... }
}

A strategy for locating protobuf source files.

The main implementation is IncludeFileResolver which uses the file system, but this trait allows sourcing files from other places as well.

Required Methods

fn open_file(&self, name: &str) -> Result<File, Error>

Opens a file by its unique name.

Errors

If the file is not found, the implementation should return Error::file_not_found.

Provided Methods

fn resolve_path(&self, _path: &Path) -> Option<String>

Converts a file system path to a unique file name.
