FunctionBehavior

Enum FunctionBehavior 

Source
pub enum FunctionBehavior {
    Immutable,
    Stable,
    Volatile,
}
Expand description

Function volatility category

Specifies whether the function modifies the database or depends on database state.

§Examples

use reinhardt_query::types::function::FunctionBehavior;

let behavior = FunctionBehavior::Immutable; // Result depends only on arguments
let behavior = FunctionBehavior::Stable;     // Result depends on DB state (same within transaction)
let behavior = FunctionBehavior::Volatile;   // Result may change (default)

Variants§

§

Immutable

IMMUTABLE - Result depends only on arguments, never changes

§

Stable

STABLE - Result depends on database state, but stable within a transaction

§

Volatile

VOLATILE - Result may change even within a transaction (default)
