Formats the value using the given formatter.

impl Display for Literal

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

Formats the value using the given formatter.

impl From<Box<String>> for Literal

fn from(value: Box<String>) -> Self

Converts to this type from the input type.

impl From<Box<bool>> for Literal

fn from(value: Box<bool>) -> Self

Converts to this type from the input type.

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl PartialEq for Literal

fn eq(&self, other: &Literal) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Calls the respective visit_* function in V

fn children<'a, V: Visit<'a>>(&'a self, v: &mut V)

Walks the children of self, visiting them in V

impl WeightOf for Literal

fn weight_of(&self) -> usize
