Enum ParameterBinding 

pub enum ParameterBinding {
    Optional,
    Mandatory,
    HasDefault,
}

Describes whether a parameter is Nullable or not or if it has a default value.

Variants

Optional

Parameter is nullable (can be set to NULL).

Mandatory

Parameter is not nullable (must not be set to NULL).

HasDefault

Parameter has a defined DEFAULT value.

Trait Implementations

impl Clone for ParameterBinding

fn clone(&self) -> ParameterBinding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterBinding

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

Formats the value using the given formatter.

impl PartialEq for ParameterBinding

fn eq(&self, other: &ParameterBinding) -> 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.
