Struct async_runtime::RtErr

pub struct RtErr { /* fields omitted */ }

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(_) => {}
}

Implementations

impl RtErr

pub fn kind(&self) -> &RtErrKind

Allows matching on the error kind

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RtErr

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Fail for RtErr

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>
