Struct rustc_session::search_paths::SearchPathFile
source · pub struct SearchPathFile {
pub path: PathBuf,
pub file_name_str: String,
}
Expand description
The obvious implementation of SearchPath::files
is a Vec<PathBuf>
. But
it is searched repeatedly by find_library_crate
, and the searches involve
checking the prefix and suffix of the filename of each PathBuf
. This is
doable, but very slow, because it involves calls to file_name
and
extension
that are themselves slow.
This type augments the PathBuf
with an String
containing the
PathBuf
’s filename. The prefix and suffix checking is much faster on the
String
than the PathBuf
. (The filename must be valid UTF-8. If it’s
not, the entry should be skipped, because all Rust output files are valid
UTF-8, and so a non-UTF-8 filename couldn’t be one we’re looking for.)
