Trait Implementations

impl Clone for Literal

fn clone(&self) -> Literal

Returns a duplicate of the value.

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 Display for Literal

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

Formats the value using the given formatter.

impl From<Literal> for Expr

fn from(v: Literal) -> Self

Converts to this type from the input type.

impl From<Token> for Literal

fn from(token: Token) -> Self

Converts to this type from the input type.

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)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Locational for Literal

fn loc(&self) -> Location

NOTE: loc cannot be treated as a light method when self is a large grammatical element. If possible, delay the computation by passing &impl Locational or other means.

fn ln_begin(&self) -> Option<u32>

1-origin

fn ln_end(&self) -> Option<u32>

fn col_begin(&self) -> Option<u32>

0-origin

fn col_end(&self) -> Option<u32>

impl NestedDisplay for Literal

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

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.

impl Traversable for Literal

type Target = Expr

fn traverse(&self, _f: &mut impl FnMut(&Self::Target))

impl<'x> TryFrom<&'x Expr> for &'x Literal

type Error = &'x Expr

The type returned in the event of a conversion error.

fn try_from(from: &'x Expr) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Expr> for Literal

type Error = Expr

The type returned in the event of a conversion error.

fn try_from(from: Expr) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Literal

impl StructuralPartialEq for Literal
