Fields

min_size: u8

The original minimum code size.

table: Table

The table of decoded codes.

buffer: Buffer

The buffer of decoded data.

last: Option<(u16, Link)>

The link which we are still decoding and its original code.

next_code: u16

The next code entry.

clear_code: u16

Code to reset all tables.

end_code: u16

Code to signal the end of the stream.

has_ended: bool

A stored flag if the end code has already appeared.

is_tiff: bool

If tiff then bumps are a single code sooner.

implicit_reset: bool

Do we allow stream to start without an explicit reset code?

code_buffer: CodeBuffer

The buffer for decoded words.
