Struct UnfilterRegion

pub struct UnfilterRegion {
    pub available: usize,
    pub filled: usize,
}

A region into a buffer utilized as a UnfilterBuf.

The span of data denoted by filled..available is the region of bytes that must be preserved for use by the decompression algorithm. It may be moved, e.g. by subtracting the same amount from both of these fields. Always ensure that filled <= available, the library does not violate this invariant when modifying this struct as an UnfilterBuf.

Fields

available: usize

The past-the-end index of byte that are allowed to be modified.

filled: usize

The past-the-end of bytes that have been written to.

Implementations

impl UnfilterRegion

pub fn as_buf<'data>( &'data mut self, buffer: &'data mut Vec<u8>, ) -> UnfilterBuf<'data>

Use this region to decompress new filtered rowline data.

Pass the wrapped buffer to StreamingDecoder::update to fill it with data and update the region indices.
