Implementations

impl Literal

pub fn value(&self) -> Value

Return value of literal.

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 Eval for Literal

fn eval(&self, _: &mut Context) -> EvalResult<Value>

Evaluate a syntax element into a type T.

impl From<Literal> for Value

fn from(literal: Literal) -> Self

Converts to this type from the input type.

impl FromStr for Literal

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Parse for Literal

fn parse(pair: Pair<'_>) -> ParseResult<Self>

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 SrcReferrer for Literal

fn src_ref(&self) -> SrcRef

Return source code reference.

fn source_hash(&self) -> u64

Return source code hash.

impl TreeDisplay for Literal

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

Write item into f and use {:depth$} syntax in front of your single line output to get proper indention.

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

Display as tree starting at depth 0.

fn write_tree(&self, f: &mut impl Write) -> Result<()>

Display as tree starting at depth 0.

impl Ty for Literal

fn ty(&self) -> Type

Return type

impl StructuralPartialEq for Literal
