Struct rhai::CustomExpr

pub struct CustomExpr {
    pub inputs: StaticVec<Expr>,
    pub tokens: StaticVec<ImmutableString>,
    pub state: Dynamic,
    pub scope_may_be_changed: bool,
    pub self_terminated: bool,
}

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

Not available under no_custom_syntax.

Fields

inputs: StaticVec<Expr>

List of keywords.

tokens: StaticVec<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

impl CustomExpr

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 ;

Trait Implementations
