ipuz_charset_vec_mask (
const IpuzCharsetVec* vec
)
Description [src]
Returns a bitmask of which ordinals occur in vec, with bit n set
when the count at ordinal n is non-zero.
This discards the counts, but makes it very cheap to ask whether
two vectors have any character in common: (eg mask_a & mask_b).
