Expand description

Abstract interface which represents a directory tree containing .proto files.

Used by the default implementation of Importer to resolve import statements. Most users will probably want to use the DiskSourceTree implementation.

This trait is sealed and cannot be implemented outside of this crate.

Provided Methods§

source

fn open<'a>( self: Pin<&'a mut Self>, filename: &Path, ) -> Result<Pin<Box<DynZeroCopyInputStream<'a>>>, FileOpenError>

Opens the given file and return a stream that reads it.

The filename must be a path relative to the root of the source tree and must not contain “.” or “..” components.
