Struct CycleError 

pub struct CycleError<K> {
    pub from: K,
    pub to: K,
    pub channel: Channel,
}

Error returned when a cycle would be created by adding a dependency.

Fields

from: K

The key that would depend on another.

to: K

The key that would be depended upon.

channel: Channel

The channel where the cycle would occur.

Trait Implementations

impl<K: Clone> Clone for CycleError<K>

fn clone(&self) -> CycleError<K>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for CycleError<K>

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

Formats the value using the given formatter.

impl<K: Debug> Display for CycleError<K>

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

Formats the value using the given formatter.

impl<K: Debug> Error for CycleError<K>

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<K: PartialEq> PartialEq for CycleError<K>

fn eq(&self, other: &CycleError<K>) -> 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.
