Implementations

impl Literal

pub fn as_str(&self) -> Option<&str>

Returns this value as a string if it is one.

pub fn as_bool(&self) -> Option<bool>

Returns this value as a boolean if it is one.

pub fn as_number(&self) -> Option<&Number>

Returns this value as a number if it is one.

pub fn into_json(self) -> Value

Converts the literal into the equivalent JSON value.

pub fn canonicalize_with(&mut self, buffer: &mut Buffer)

Puts the literal into canonical form, using the given buffer to render numbers. Only numbers have a non-trivial canonical form.

pub fn canonicalize(&mut self)

Puts this literal into canonical form.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Literal

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

Formats the value using the given formatter.

impl Eq for Literal

impl Hash for Literal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

impl Ord for Literal

fn cmp(&self, other: &Self) -> 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.

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