Enum AsyncState

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

Represents the state of an async operation

Variants

Loading

The operation is currently loading

Success(T)

The operation completed successfully with data

Error(E)

The operation failed with an error

Implementations

impl<T, E> AsyncState<T, E>

pub fn is_loading(&self) -> bool

Returns true if the state is currently loading

pub fn is_success(&self) -> bool

Returns true if the state contains successful data

pub fn is_error(&self) -> bool

Returns true if the state contains an error

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

Returns the data if successful, None otherwise

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

Returns the error if failed, None otherwise

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

fn eq(&self, other: &AsyncState<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.
