assert_is_single_x(x, class)

assert_inherits(x, class)

assert_valid_option(x, options)

is_one_of(x, classes)

is_column_subset(df1, df2, interger_tolerance = TRUE, factor_tolerance = TRUE)

is_single_character(x)

is_single_logical(x)

is_single_numeric(x)

has_equal_elements(x)

has_distinct_elements(x)

none(..., na.rm = FALSE)
