pub fn isspace<D: Dimension>(a: &StringArray<D>) -> FerrayResult<Array<bool, D>>Expand description
Return true where every character is whitespace and the string is
non-empty. Matches numpy.strings.isspace, which delegates per
element to CPython’s str.isspace() (Py_UNICODE_ISSPACE): the
Unicode White_Space property plus the bidi separators
U+001C..U+001F. See [is_space_char]/[WHITESPACE_RANGES].
