//! The example from the readme!
|
|
//!
|
|
//! This example demonstrates how to create a simple counter app with dioxus. The `Signal` type wraps inner values,
|
|
//! making them `Copy`, allowing them to be freely used in closures and and async functions. `Signal` also provides
|
|
//! helper methods like AddAssign, SubAssign, toggle, etc, to make it easy to update the value without running
|
|
//! into lock issues.
