Implementations

impl<'a, 'tcx, E> CacheEncoder<'a, 'tcx, E> where
    E: 'a + OpaqueEncoder, [src]

fn source_file_index(&mut self, source_file: Lrc<SourceFile>) -> SourceFileIndex[src]

fn encode_tagged<T: Encodable<Self>, V: Encodable<Self>>(
    &mut self,
    tag: T,
    value: &V
) -> Result<(), E::Error>[src]

Encode something with additional information that allows to do some sanity checks when decoding the data again. This method will first encode the specified tag, then the given value, then the number of bytes taken up by tag and value. On decoding, we can then verify that we get the expected tag and read the expected number of bytes.
