Enum bevy_mod_scripting::prelude::rune::ast::Condition

#[non_exhaustive]
pub enum Condition {
    Expr(Expr),
    ExprLet(ExprLet),
}

The condition in an if statement.

• true.
• let Some(<pat>) = <expr>.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Expr(Expr)

A regular expression.

ExprLet(ExprLet)

A pattern match.

Trait Implementations

impl Debug for Condition

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

Formats the value using the given formatter.

impl OptionSpanned for Condition

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for Condition

fn parse(p: &mut Parser<'_>) -> Result<Condition, Error>

Parse the current item from the parser.

impl PartialEq for Condition

fn eq(&self, other: &Condition) -> 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 Spanned for Condition

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for Condition

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream ) -> Result<(), Error>

Turn the current item into tokens.

impl TryClone for Condition

fn try_clone(&self) -> Result<Condition, Error>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Eq for Condition

impl StructuralPartialEq for Condition
