Enum RuntimeComponentGraphError 

pub enum RuntimeComponentGraphError {
    MissingDependency {
        component: &'static str,
        dependency: &'static str,
    },
    Cycle {
        cycle: String,
    },
}

Component dependency graph validation error.

Variants

MissingDependency

A component depends on a component that was never registered.

Fields

component: &'static str

Component declaring the dependency.

dependency: &'static str

Missing dependency component name.

Cycle

Component dependencies contain a cycle.

Fields

cycle: String

Human-readable cycle path.

Trait Implementations

impl Clone for RuntimeComponentGraphError

fn clone(&self) -> RuntimeComponentGraphError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RuntimeComponentGraphError

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

Formats the value using the given formatter.

impl Display for RuntimeComponentGraphError

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

Formats the value using the given formatter.

impl Error for RuntimeComponentGraphError

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 PartialEq for RuntimeComponentGraphError

fn eq(&self, other: &RuntimeComponentGraphError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
