Enum ByteSource 

pub enum ByteSource {
    Buf(Vec<u8>),
    Map(Mmap),
}

Bytes of one file, mapped when a plain file is large enough.

Compressed input is decoded into a buffer. A plain file under 64 KiB, or anything that is not a regular file, is read into a buffer. A larger plain file stays mapped for the parse and is not copied. The bytes are not checked as UTF-8; the parser reports a bad byte when it reaches it.

Variants

Buf(Vec<u8>)

Map(Mmap)

Implementations
