Implementations§

§

impl<Q> MutationStateData<Q>
where Q: MutationCapability,

pub fn is_ok(&self) -> bool

Check if the state is MutationStateData::Settled and Result::Ok.

pub fn is_err(&self) -> bool

Check if the state is MutationStateData::Settled and Result::Err.

pub fn is_loading(&self) -> bool

Check if the state is MutationStateData::Loading.

pub fn is_pending(&self) -> bool

Check if the state is MutationStateData::Pending.

pub fn ok(&self) -> Option<&<Q as MutationCapability>::Ok>

Get the value as an Option.

pub fn unwrap( &self, ) -> &Result<<Q as MutationCapability>::Ok, <Q as MutationCapability>::Err>

Get the value as an Result if possible, otherwise it will panic.

Trait Implementations§

§

impl<Q> Debug for MutationStateData<Q>
where Q: MutationCapability, <Q as MutationCapability>::Ok: Debug, <Q as MutationCapability>::Err: Debug,

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>
