Trait laz::record::FieldDecompressor

pub trait FieldDecompressor<R: Read> {
    fn size_of_field(&self) -> usize;
    fn decompress_first(
        &mut self, 
        src: &mut R, 
        first_point: &mut [u8]
    ) -> Result<()>;
    fn decompress_with(
        &mut self, 
        decoder: &mut ArithmeticDecoder<R>, 
        buf: &mut [u8]
    ) -> Result<()>;
}

Trait to be implemented by FieldDecompressors

Note

Here a 'field' may be a single field (example: GpsTime which is a double) or a combination of single fields (example: the RGB is considered a field and it is a combination of multiple single fields: Red, Green, Blue)

Required methods

fn size_of_field(&self) -> usize

size in bytes of the decompressed field data

fn decompress_first(
    &mut self,
    src: &mut R,
    first_point: &mut [u8]
) -> Result<()>

Decompress the first point's field from the src, and pack it into the first_point slice

The first_point slice will have a len of exactly self_of_field() bytes.

fn decompress_with(
    &mut self,
    decoder: &mut ArithmeticDecoder<R>,
    buf: &mut [u8]
) -> Result<()>

Decompress the next point's field from the decoder and pack the decompressed data in the buf slice.

The buf slice will have a len of exactly self_of_field() bytes.
