Implementations

impl<'a, 'tcx> CacheEncoder<'a, 'tcx>

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

fn encode_tagged<T: Encodable<Self>, V: Encodable<Self>>(
    &mut self,
    tag: T,
    value: &V
)

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.

fn finish(self) -> Result<usize, Error>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
