Enum wagon_parser::parser::atom::Atom

pub enum Atom {
    Ident(Ident),
    Dict(Dictionary),
    LitBool(bool),
    LitNum(i32),
    LitFloat(NotNan<f32>),
    LitString(String),
    Group(SpannableNode<Expression>),
}

The base elements of each expression.

The data in here is kind of similar to [wagon_value::Value] and TryFrom is implemented for it as a result. However, an Atom includes additional syntactic data, which is not important (or even not available) for Value (for example, an Ident). As a result, Atom::Ident, Atom::Dict and Atom::Group can not be directly converted and manual implementation is required.

Grammar

Atom -> Ident
|  Dictionary
|  bool
|  i32

Trait Implementations

impl Clone for Atom

fn clone(&self) -> Atom

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Atom

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

Formats the value using the given formatter.

impl Display for Atom

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

Formats the value using the given formatter.

impl Hash for Atom

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 Parse for Atom

fn parse(lexer: &mut LexerBridge<'_>) -> ParseResult<Self>

Given a lexer, try to parse a valid instance of this node.

fn parse_sep( lexer: &mut LexerBridge<'_>, join: Tokens ) -> ParseResult<Vec<Self>>

where Self: Sized,

Parse multiple instances of this node, separated by a Tokens.

fn parse_sep_end( lexer: &mut LexerBridge<'_>, join: Tokens, end: Tokens ) -> ParseResult<Vec<Self>>

where Self: Sized,

Parse multiple instances of this node, separated by a Tokens end ended by a (possibly different) Tokens.

impl PartialEq for Atom

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<Atom> for RecursiveValue

type Error = ConversionError<Atom, RecursiveValue>

The type returned in the event of a conversion error.

fn try_from(value: Atom) -> Result<Self, Self::Error>

Performs the conversion.

impl<T: Valueable> TryFrom<Atom> for Value<T>

type Error = ConversionError<Atom, Value<T>>

The type returned in the event of a conversion error.

fn try_from(value: Atom) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Atom

impl StructuralPartialEq for Atom
