Indices with Word

npWithIndicesSListI xs ⇒ NP (K Word8) xs Source #

We only allow up to 23 (so counting from 0, 24 elements in xs), because CBOR stores a Word8 in the range 0-23 as a single byte equal to the value of the Word8.

nsFromIndexSListI xs ⇒ Word8Maybe (NS (K ()) xs) Source #

We only allow up to 23, see npWithIndices.

nsToIndexSListI xs ⇒ NS f xs → Word8 Source #

toWord8Index xs x → Word8 Source #
