[−][src]Struct async_runtime::RtErr
The error type for errors happening in async_runtime
.
Use RtErr::kind()
to know which kind of error happened. RtErrKind implements Eq,
so you can do the following if all you want to know is the kind of error:
use async_runtime::*; rt::init( RtConfig::Local ).expect( "Set default executor" ); match rt::init( RtConfig::Pool ) { Err(e) => { if let RtErrKind::DoubleExecutorInit = e.kind() { println!( "{}", e ); } // This also works: // match e.kind() { RtErrKind::DoubleExecutorInit => println!( "{}", e ), _ => {}, } }, Ok(_) => {} }
