Implementations§

source§

impl EnumClass

source

pub fn new<T: StaticType + HasParamSpec<ParamSpec = ParamSpecEnum>>() -> Self

Create a new EnumClass from a static type T.

Panics if T is not representing an enum.

source

pub fn with_type(type_: Type) -> Option<Self>

Create a new EnumClass from a Type.

Returns None if type_ is not representing an enum.

source

pub fn type_(&self) -> Type

Type of the enum.

source

pub fn value(&self, value: i32) -> Option<&EnumValue>

Gets EnumValue by integer value, if existing.

Returns None if the enum does not contain any value with value.

source

pub fn value_by_name(&self, name: &str) -> Option<&EnumValue>

Gets EnumValue by string name name, if existing.

Returns None if the enum does not contain any value with name name.

source

pub fn value_by_nick(&self, nick: &str) -> Option<&EnumValue>

Gets EnumValue by string nick nick, if existing.

Returns None if the enum does not contain any value with nick nick.

source

pub fn values(&self) -> &[EnumValue]

Gets all EnumValue of this EnumClass.

source

pub fn to_value(&self, value: i32) -> Option<Value>

Converts integer value to a Value, if part of the enum.

source

pub fn to_value_by_name(&self, name: &str) -> Option<Value>

Converts string name name to a Value, if part of the enum.

source

pub fn to_value_by_nick(&self, nick: &str) -> Option<Value>

Converts string nick nick to a Value, if part of the enum.
