Enum LiteralCompressionMode 

pub enum LiteralCompressionMode {
    Auto,
    Enable,
    Disable,
}

Whether literals are entropy-coded, the drop-in equivalent of C zstd’s ZSTD_c_literalCompressionMode (ZSTD_ps_auto / ZSTD_ps_enable / ZSTD_ps_disable).

Variants

Auto

The level decides: literals are stored raw on the fast strategy’s acceleration (negative) levels, where the Huffman pass costs more speed than it saves, and compressed everywhere else.

Enable

Compress literals on every level, the negative ones included. A block whose literals do not shrink still stores them raw.

Disable

Never compress literals: every literal section is stored raw.
