Enum SupervisorError 

pub enum SupervisorError {
    Signal(Error),
    Process(BoxError),
}

Error type returned from task operations

Variants

Signal(Error)

Error setting up signal listeners

Process(BoxError)

Error from within the managed process

Implementations

impl SupervisorError

pub fn from_err<E: Into<BoxError>>(err: E) -> Self

Creates a SupervisorError::Process from any error type that can be converted to BoxError.

This is useful in map_err calls to convert user process errors:

my_future.map_err(SupervisorError::from_err)

Trait Implementations

impl Debug for SupervisorError

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

Formats the value using the given formatter.

impl Display for SupervisorError

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

Formats the value using the given formatter.

impl Error for SupervisorError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
