Enum Load 

pub enum Load<T> {
    NotAsked,
    Loading,
    Ready(T),
    Failed(Arc<Error>),
}

Status of a value that arrives asynchronously (a feature’s State field fed by a loader or a live push), so “not here yet” is representable as data instead of requiring a separate suspense mechanism at the read site.

Variants

NotAsked

Loading

Ready(T)

Failed(Arc<Error>)

Implementations

impl<T> Load<T>

pub fn failed(err: impl Into<Error>) -> Self

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

pub fn is_loading(&self) -> bool

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

Trait Implementations

impl<T: Clone> Clone for Load<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Load<T>

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

Formats the value using the given formatter.

impl<T> Default for Load<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Eq> Eq for Load<T>

impl<T: PartialEq> PartialEq for Load<T>

anyhow::Error has no equality of its own; two Faileds compare by Arc identity (a re-fetched failure is a new value and must re-render).

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
