Enum Closure 

pub enum Closure {
    One(Arc<str>, Conditional),
    Two(Arc<str>, Arc<str>, Conditional),
    Primary(Box<Primary>),
}

Closure (anonymous function) expression.

Variants:

• One(name, body) – single-parameter closure.
• Two(name1, name2, body) – two-parameter closure.
• Primary(primary) – primary/conditional expression treated as a closure body.

Variants

One(Arc<str>, Conditional)

Two(Arc<str>, Arc<str>, Conditional)

Primary(Box<Primary>)

Primary flattened AST optimization.

Implementations

impl Closure

pub fn invoke(&self, context: &mut dyn ContextLike) -> Result<Arc<Value>>

Evaluate the closure body using parameter bindings already set in context.

pub fn call( &self, context: &mut dyn ContextLike, arg: Arc<Value>, ) -> Result<Arc<Value>>

Call the closure with argument value(s) using the AIMX calling convention.

• Propagates Value::Errata without evaluation.
• Binds a single value to parameter index 0.
• For arrays, binds element 0 to parameter 0 and element 1 (if present) to parameter 1.
• Evaluates inside a closure scope (start_closure / end_closure).

pub fn print(&self, writer: &mut Writer)

Write the closure in AIMX syntax.

Trait Implementations

impl Clone for Closure

fn clone(&self) -> Closure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Closure

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

Formats the value using the given formatter.

impl Display for Closure

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

Formats the value using the given formatter.

impl ExpressionLike for Closure

fn evaluate(&self, context: &mut dyn ContextLike) -> Result<Arc<Value>>

Evaluate to a runtime value.

• Primary evaluates directly.
• Other variants return Value::Closure for later invocation.

fn to_formula(&self) -> String

Return the formula-string representation (round-trippable by the parser).

impl PartialEq for Closure

fn eq(&self, other: &Closure) -> 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 WriterLike for Closure

fn write(&self, writer: &mut Writer)

Serialize this expression with the given Writer.

fn to_stringized(&self) -> String

Return a string representation (raw unsafe output).

fn to_sanitized(&self) -> String

Return a sanitized string representation (escaped for safe output).

fn to_expressionized(&self) -> String

Return a sanitized string representation (escaped for safe output).
