pub const FSST_SYMBOL_TABLE_LEN: usize = 255;Expand description
The number of entries in a fully-populated FSST symbol table.
Code 255 is reserved as the escape code, leaving 255 usable codes. Decompressor borrows
the symbol table as fixed-size arrays of exactly this length, so Vortex pads the symbols and
symbol lengths buffers out to it on construction.
