Enum TopoError 

pub enum TopoError {
    Cycle {
        cycle: Vec<&'static str>,
    },
    UnknownDependency {
        subsystem: &'static str,
        dependency: &'static str,
    },
}

Error produced during topo-sort of the subsystem dependency graph.

Variants

Cycle

A cycle was detected in the dependency graph.

cycle lists the subsystem names forming the cycle in order.

Fields

cycle: Vec<&'static str>

UnknownDependency

A subsystem listed a dependency that is not registered.

Fields

subsystem: &'static str

dependency: &'static str

Trait Implementations

impl Debug for TopoError

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

Formats the value using the given formatter.

impl Display for TopoError

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

Formats the value using the given formatter.

impl Error for TopoError

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.

impl From<TopoError> for BootstrapError

fn from(source: TopoError) -> Self

Converts to this type from the input type.

impl From<TopoError> for ClusterError

fn from(e: TopoError) -> Self

Converts to this type from the input type.
