Simple GlobalContainer based on std::sync::RwLock.
This crate is AS IS.
NOTE: GlobalContainer
use RWLock
, GlobalMutexContainer
use Mutex
.
By ZRY.
§Features
§tokio
For tokio, use feature tokio
[dependency]
simple-rw-global = { version="0.3.0", feature=["tokio"] }
With this feature, module tokio
is available.
§Example
use simple_rw_global::GlobalContainer;
static GLOBAL : GlobalContainer<GlobalObject> = GlobalContainer::<GlobalObject>::new();
pub struct GlobalObject {
log_prefix: String,
}
impl GlobalObject {
pub fn new(prefix: &str) -> GlobalObject {
GlobalObject{log_prefix: String::from(prefix)}
}
pub fn log(&self, msg: &str) {
println!("[{}] {}", self.log_prefix.as_str(), msg);
}
pub fn change_prefix(&mut self, prefix: &str) {
self.log_prefix = String::from(prefix);
}
}
fn main() {
println!("before init, is empty: {}", GLOBAL.is_empty());
GLOBAL.set(GlobalObject::new("log-test1"));
println!("after init, is empty: {}", GLOBAL.is_empty());
println!("init ok.");
GLOBAL.get().log("hello 1");
GLOBAL.get_mut().change_prefix("log-test2");
GLOBAL.get().log("hello 2");
GLOBAL.manual_drop();
println!("dropped manually. will panic then.");
GLOBAL.get().log("test after drop.");
}
