Struct UseStorage 

pub struct UseStorage {
    pub key: &'static str,
    pub value: Signal<String>,
    pub kind: UseStorageKind,
}

Reactive state for one stored value.

The handle carries the key it watches, the current value, and the kind of storage it lives in.

The value is a Signal<String>: a render closure that reads it re-renders when the value changes, and nothing else in the tree is disturbed.

Fields

key: &'static str

The storage key this handle watches.

value: Signal<String>

The current stored value.

kind: UseStorageKind

Which storage the value lives in.

Implementations

impl UseStorage

Inherent implementation of UseStorage.

pub fn current(&self) -> String

Returns the current value as a snapshot.

Returns

• String - The stored value.

pub fn set_value(&self, value: &str)

Writes value to storage and updates the signal.

Arguments

• &str - The value to store.

pub fn clear(&self)

Removes the key from storage and clears the signal.

Trait Implementations

impl Clone for UseStorage

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UseStorage

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

Formats the struct fields as a debug struct, skipping excluded fields.

Arguments

• &mut std::fmt::Formatter<'_> - The formatter to write the representation into.

Returns

• std::fmt::Result - Success or failure of the formatting operation.
