Struct FunctionBinding 

pub struct FunctionBinding {
    pub object_id: Option<[u8; 16]>,
    pub name: String,
    pub argument_types: Vec<String>,
    pub builtin: bool,
    pub dispatch: Option<FunctionDispatch>,
    pub invocation: Option<Box<RoutineInvocationBinding>>,
    pub resolution_error: Option<FunctionResolutionError>,
}

Fields

object_id: Option<[u8; 16]>

Stable identity of a bound user routine. Built-ins and unbound calls leave this unset.

name: String

argument_types: Vec<String>

builtin: bool

dispatch: Option<FunctionDispatch>

Executor operation selected structurally during parsing or overload binding. SQL-visible routine lookup never consults display-name conventions for these operations.

invocation: Option<Box<RoutineInvocationBinding>>

Concrete invocation contract selected during routine overload resolution.

resolution_error: Option<FunctionResolutionError>

A typed overload-resolution failure retained until the expression reaches a fallible planning or execution boundary. This never reuses the SQL function-name namespace as an error channel.

Implementations

impl FunctionBinding

pub fn polymorphic_builtin_syntax(name: &str) -> Self

Construct the identity marker used when PostgreSQL parses a polymorphic syntax expression instead of an ordinary function call.

pub fn dispatched(dispatch: FunctionDispatch) -> Self

Construct a parser- or binder-owned expression with an identity that cannot collide with a SQL routine name.

pub fn undefined_function( name: impl Into<String>, signature: impl Into<String>, ) -> Self

Preserve an undefined-overload error structurally without fabricating a dispatch name.

pub fn is_polymorphic_builtin_syntax(&self) -> bool

Return whether this binding marks a polymorphic syntax expression whose argument types must be inferred from its operands.

pub fn is_polymorphic_builtin_syntax_name(name: &str) -> bool

Return whether an unqualified local name belongs to PostgreSQL’s polymorphic function-like syntax expressions.
