Expand description

A trait that provides methods for reading basic primitive types.

Required Methods§

Source

fn read_u8(&mut self) -> Result<u8>

Do not return Error::Eof from this method. Return Error::UnexpectedEof instead.

Provided Methods§

Source

fn read_presence_map(&mut self) -> Result<(u64, u8)>

Read the presence map. Return the bitmap and the number of bits in the bitmap.

In case of error, return Error::Eof if the end of the stream is reached at the first byte of the presence map. Otherwise, return any other error, e.g.: Error::UnexpectedEof.
