Struct Flag 

pub struct Flag(pub Arc<RwLock<bool>>);

Structure that consists of a bool wrapped in Arc and RwLock to ensure thread safety and protect against race conditions. Since the RwLock used is from the tokio, it can be used asynchronously. Important: Before passing the flag to a new thread clone it.

Tuple Fields

0: Arc<RwLock<bool>>

Implementations

impl Flag

pub fn new(value: bool) -> Self

Creates a new Flag.

pub async fn read(&self) -> bool

Reads the boolean value of the Flag (without blocking other threads from reading the value as well).

pub async fn write(&self, value: bool)

Write a new boolean value to the Flag (blocks read and write operations from all threads until completed).

pub fn clone(&self) -> Self

Creates a new reference to the flag so it can be used by a new thread.

Trait Implementations

impl Clone for Flag

fn clone(&self) -> Flag

Returns a duplicate of the value.

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

Performs copy-assignment from source.
