Struct tauri::State

source · 
pub struct State<'r, T: Send + Sync + 'static>(/* private fields */);
Expand description

A guard for a state value.

See Manager::manage for usage examples.

Implementations§

source§

impl<'r, T: Send + Sync + 'static> State<'r, T>

source

pub fn inner(&self) -> &'r T

Retrieve a borrow to the underlying value with a lifetime of 'r. Using this method is typically unnecessary as State implements std::ops::Deref with a std::ops::Deref::Target of T.
