Struct ResolvedScalarFunction 

pub struct ResolvedScalarFunction { /* private fields */ }

One scalar implementation and the immutable metadata selected for a call.

Keeping these values together prevents execution paths from resolving the function, schema-safety policy, query-constancy policy, and argument-collation contract through separate registry probes that could disagree or repeat canonicalization.

Implementations

impl ResolvedScalarFunction

pub fn function(&self) -> Arc<dyn ScalarFunction>

Clone the selected function object for invocation outside a registry borrow or lock.

pub const fn schema_safety(&self) -> ScalarSchemaSafety

Frozen schema-safety policy belonging to the selected registration.

pub const fn query_constancy(&self) -> ScalarQueryConstancy

Frozen query-constancy policy belonging to the selected registration.

pub const fn consumes_argument_collation(&self) -> bool

Frozen argument-collation contract belonging to the selected entry.

Trait Implementations

impl Clone for ResolvedScalarFunction

fn clone(&self) -> ResolvedScalarFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.
