Function kdbplus::api::enumerate_n

pub fn enumerate_n(string: S, n: I) -> S

Extract the first n chars from a character array and enumerate it internally. This function must be used to add a character array as a symbol value to a symbol list. The returned value is the same character array as the input.

Example

See the example of flip.

Note

The reason why this function must be used is to enumerate the character array before handling it as a q symbol type value. q/kdb+ is enumerating all symbol values to optimize comparison or memory usage. On the other hand new_symbol does the enumeration internally and therefore it does not need this function.
