Enum MutationState 

pub enum MutationState<T, E> {
    Idle,
    Loading,
    Success(T),
    Error(E),
}

Represents the state of a mutation operation

Variants

Idle

The mutation is idle (not running)

Loading

The mutation is currently loading

Success(T)

The mutation completed successfully

Error(E)

The mutation failed with an error

Implementations

impl<T, E> MutationState<T, E>

pub fn is_idle(&self) -> bool

Returns true if the mutation is idle

pub fn is_loading(&self) -> bool

Returns true if the mutation is currently loading

pub fn is_success(&self) -> bool

Returns true if the mutation completed successfully

pub fn is_error(&self) -> bool

Returns true if the mutation failed

pub fn data(&self) -> Option<&T>

Returns the success data if available

pub fn error(&self) -> Option<&E>

Returns the error if available

Trait Implementations

impl<T, E> AsyncState for MutationState<T, E>

type Data = T

The type of successful data

type Error = E

The type of error

fn is_loading(&self) -> bool

Returns true if the state is currently loading

fn is_success(&self) -> bool

Returns true if the state contains successful data

fn is_error(&self) -> bool

Returns true if the state contains an error

fn data(&self) -> Option<&T>

Returns the data if successful, None otherwise

fn error(&self) -> Option<&E>

Returns the error if failed, None otherwise

impl<T: Clone, E: Clone> Clone for MutationState<T, E>

fn clone(&self) -> MutationState<T, E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: PartialEq, E: PartialEq> PartialEq for MutationState<T, E>

fn eq(&self, other: &MutationState<T, E>) -> 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.
