Implementations

impl FunctionRegistry

pub fn empty() -> Self

pub fn register_unary_prefix(&mut self, op: impl FunctionDef)

Register a unary prefix operator (e.g., NOT, -)

pub fn register_unary_postfix(&mut self, op: impl FunctionDef)

Register a unary postfix operator (e.g., ..)

pub fn register_binary(&mut self, op: impl FunctionDef)

Register a binary operator (e.g., +, -, AND, OR)

pub fn register_function(&mut self, func: impl FunctionDef)

Register a function by name

pub fn autocomplete_suggestions(&self) -> Vec<CompletionItem>

pub fn bind( &self, function_name: &str, positional: Vec<Arc<Expression>>, named: OrderMap<String, Arc<Expression>>, function_type: InvocationType, ctx: &mut ExpressionTranslationContext<'_>, ) -> Result<FunctionResolution<Arc<TypedExpression>>, FunctionBindingError>

Bind AST arguments to a function, handling custom_bind and broadcast.

This method implements a two-pass binding strategy:

1. First pass: try custom_bind on all candidates (for functions like transform)
2. Second pass: standard binding on remaining candidates (only if no lambdas)

For standard candidates, tries direct binding first. If that fails and an argument is an array, tries broadcast binding (applying function element-wise).

Returns immediately on Direct match. Collects Broadcast matches and returns one if exactly one found (ambiguity error if multiple).
