Enum FunctionBehavior 

pub enum FunctionBehavior {
    Immutable,
    Stable,
    Volatile,
}

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)

Trait Implementations

impl Clone for FunctionBehavior

fn clone(&self) -> FunctionBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionBehavior

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FunctionBehavior

fn eq(&self, other: &FunctionBehavior) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
