Performs copy-assignment from source.

impl Debug for FontDescription

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FontDescription

fn default() -> Self

Returns the “default value” for a type.

impl Display for FontDescription

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<FontDescription> for Value

fn from(o: FontDescription) -> Self

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for FontDescription

fn cmp(&self, other: &FontDescription) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
