Function zstd_sequences 

pub fn zstd_sequences(
    s: Sequences<'_>,
) -> Result<(usize, usize, [u32; 3]), SeqError>

Decodes and executes a zstd block’s sequences (RFC 8878 section 3.1.1.3.2 and 3.1.1.4). Returns the end of the output written (the remaining literals after the last sequence are left to the caller) and the repeat offsets; the bytes after the end up to the slack are garbage. Same results as simoom-compress’s safe execute.

Panics

If the preconditions on Sequences do not hold (they are checked on entry).
