except <buffer>, values are booleans (default false). Also:
                • "noremap" disables |recursive_mapping|, like |:noremap|
                • "desc" human-readable description.
                • "callback" Lua function called in place of {rhs}.
                • "replace_keycodes" (boolean) When "expr" is true, replace
                  keycodes in the resulting string (see
                  |nvim_replace_termcodes()|). Returning nil from the Lua
                  "callback" is equivalent to returning an empty string.

nvim__id({obj})                                                   *nvim__id()*
    Returns object given as argument.

    This API function is used for testing. One should not rely on its presence
    in plugins.

    Parameters: ~
      • {obj}  Object to return.

    Return: ~
        its argument.

nvim__id_array({arr})                                       *nvim__id_array()*
    Returns array given as argument.

    This API function is used for testing. One should not rely on its presence
    in plugins.

    Parameters: ~
      • {arr}  Array to return.

        its argument.

nvim__id_float({flt})                                       *nvim__id_float()*
    Returns floating-point value given as argument.

    This API function is used for testing. One should not rely on its presence

nvim__inspect_cell({grid}, {row}, {col})                *nvim__inspect_cell()*
    NB: if your UI doesn't use hlstate, this will not return hlstate first
    time.

nvim__invalidate_glyph_cache()                *nvim__invalidate_glyph_cache()*
    For testing. The condition in schar_cache_clear_if_full is hard to reach,
    so this function can be used to force a cache clear in a test.
