Function rustc_metadata::fs::emit_wrapper_file
source · pub fn emit_wrapper_file(
sess: &Session,
data: &[u8],
tmpdir: &MaybeTempDir,
name: &str
) -> PathBuf
Expand description
We use a temp directory here to avoid races between concurrent rustc processes,
such as builds in the same directory using the same filename for metadata while
building an .rlib
(stomping over one another), or writing an .rmeta
into a
directory being searched for extern crate
(observing an incomplete file).
The returned path is the temporary file containing the complete metadata.
