Enum Fetch 

pub enum Fetch<T> {
    Idle,
    Loading {
        id: i64,
    },
    Loaded(T),
    Error(String),
}

Lifecycle of a data-tab fetch request.

Transitions: Idle → Loading (on submit) → Loaded or Error (on reply). A refresh resets back to Idle so the next switch_tab re-fetches.

Variants

Idle

No request has been issued yet (initial state or after reset).

Loading

A request was issued with the given envelope id; reply is pending.

Fields

id: i64

Loaded(T)

Reply received and parsed successfully.

Error(String)

Reply received but produced an error.

Trait Implementations

impl<T: Clone> Clone for Fetch<T>

fn clone(&self) -> Fetch<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Fetch<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Fetch<T>

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