makeKey

makeKey(args...)

args are multiple scalars or vectors of the same length.

Combine the specified args as a BLOB scalar or vector, so it can used as the key(s) of a dictionary or a set. Compared with makeSortedKey, makeKey keeps the order of the inputs in the result.

makeKey(`a1,`b1,`c1)
// output
a1b1c1

set(makeKey(1 2, 4 5))

re=makeKey(`a1`a2, `_1`_2)
dict(re,100 200)

// output
a2_2->200
a1_1->100
