Implementations

impl OptionEnum

pub fn is_some(&self) -> bool

Check if an enum value is set

use sea_query::{Enum, EnumTypeName, OptionEnum};

let type_name: EnumTypeName = "Test".into();

assert_eq!(false, OptionEnum::None(type_name.clone()).is_some());
assert_eq!(
    true,
    OptionEnum::Some(Box::new(Enum {
        type_name,
        value: "Foo".into()
    }))
    .is_some()
);

Trait Implementations

impl Clone for OptionEnum

fn clone(&self) -> OptionEnum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionEnum

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

Formats the value using the given formatter.

impl Hash for OptionEnum

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OptionEnum

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