Expand description

(internals) A custom syntax expression. Exported under the internals feature only.

Not available under no_custom_syntax.

Fields§

§inputs: Box<[Expr]>

List of keywords.

§tokens: Box<[ImmutableString]>

List of tokens actually parsed.

§state: Dynamic

State value.

§scope_may_be_changed: bool

Is the current Scope possibly modified by this custom statement (e.g. introducing a new variable)?

§self_terminated: bool

Is this custom syntax self-terminated?

Implementations§

source§

impl CustomExpr

source

pub const fn is_self_terminated(&self) -> bool

Is this custom syntax self-terminated (i.e. no need for a semicolon terminator)?

A self-terminated custom syntax always ends in $block$, } or ;
