Enum RegistrationError

pub enum RegistrationError {
    UnstableFeaturesRequired,
    InvalidCasts(InvalidCasts),
    DTrace(Error),
}

Errors returned by register_hooks.

Variants

UnstableFeaturesRequired

tokio-dtrace hooks cannot be registered, as Tokio’s unstable features are not enabled.

InvalidCasts(InvalidCasts)

tokio-dtrace hooks were not registered as the layout of Tokio’s tokio::task::Id type has changed. See check_casts for details.

DTrace(Error)

Probes could not be registered with DTrace.

Trait Implementations

impl Debug for RegistrationError

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

Formats the value using the given formatter.

impl Display for RegistrationError

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

Formats the value using the given formatter.

impl Error for RegistrationError

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.
