pub fn decode_prefix(bytes: &[u8]) -> Result<(Vec<Vec<u8>>, usize)>Expand description
Decodes a chunk that sits at the front of a longer buffer, and says how many bytes it took.
A column group holds one of these per column, and the decoder on that side cannot know where one ends until it has been read.
ยงErrors
As decode, except that trailing bytes are what the caller asked about rather than an error.
