pub struct CachedProcess<'a, T> { /* private fields */ }
Expand description

Cached process to avoid looking up a global process multiple times.

Implementations§

source§

impl<'a, T> CachedProcess<'a, T>

source

pub fn new(name: &'a str) -> Self

Construct a new process cache with a registered process name.

source

pub fn process_name(&'a self) -> &'a str

Returns the process name.

source

pub fn is_present(&'a self) -> bool

Returns true if the process has been looked up and exists.

Example
use lunatic::Process;

let process: CachedProcess<'static, Process<()>> = CachedProcess::new("foo");
assert!(!process.is_present()); // Initially not present

process.get();
assert!(!process.is_present()); // Not present, even after lookup

spawn!(|| { loop { /* ... */ } }).register("foo"); // Start a process called "foo"

process.reset();
process.get();
assert!(process.is_present()); // Is present
source

pub fn is_looked_up(&'a self) -> bool

Returns true if the process has been looked up, regardless if the process was found.

Example
use lunatic::Process;

let process: CachedProcess<'static, Process<()>> = CachedProcess::new("");
assert!(!process.is_looked_up());

process.get();
assert!(process.is_looked_up());
