Check that a unique key is indeed unique in a tibble (TRUE/str)

Description

A checkmate-style check function.

Usage

check_ukey_unique(x, ukey_names, end_cli_message = character())

Arguments

x	a tibble, with no particular row or column order (if you have a guaranteed row order based on the ukey you can probably do something more efficient)
ukey_names	character vector; subset of column names of x denoting a unique key.
end_cli_message	optional character vector, a cli message format string/vector; information/advice to tack onto any error messages.

Value

TRUE if no ukey is duplicated (i.e., x[ukey_names] has no duplicated rows); string with an error message if there are errors.
