fn type_(&self) -> SassValueType

Type of this SassValue; useful for matching on

fn stringify(self, compressed: bool, precision: u8) -> Self

Create a new string SassValue using this object which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_null() -> Self

Creates a new null SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_boolean(value: bool) -> Self

Creates a new boolean SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_number(value: f64, unit: &CStr) -> Self

Creates a new number SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_unquoted_string(value: &CStr) -> Self

Creates a new unquoted string SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_quoted_string(value: &CStr) -> Self

Creates a new quoted string SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_warning(message: &CStr) -> Self

Creates a new warning SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_error(message: &CStr) -> Self

fn new_color(red: f64, green: f64, blue: f64, alpha: f64) -> Self

Creates a new color SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.

fn new_list(size: usize, separator: ListSeparator, _is_bracketed: bool) -> Self

Creates a new list SassValue which will be free-ed when it is dropped unless transfer_ownership_to_c() is called.
