Trait HasExtractableParts

pub trait HasExtractableParts:
    Clone
    + IntoDatum
    + DateTimeType {
    const EXTRACT_FUNCTION: unsafe fn(FunctionCallInfo) -> Datum;

    // Provided method
    fn extract_part(&self, field: DateTimeParts) -> Option<AnyNumeric> { ... }
}

Required Associated Constants

const EXTRACT_FUNCTION: unsafe fn(FunctionCallInfo) -> Datum

Provided Methods

fn extract_part(&self, field: DateTimeParts) -> Option<AnyNumeric>

Extract a DateTimeParts part from a date/time-like type

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
