Implementations

impl TopologyError

pub fn help(&self) -> String

Returns guidance on how to resolve this error

Following the DDD practices for expressive error types, this method explains what went wrong and suggests how to fix it.

Trait Implementations

impl Debug for TopologyError

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

Formats the value using the given formatter.

impl Display for TopologyError

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

Formats the value using the given formatter.

impl Error for TopologyError

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<PortConflict> for TopologyError

fn from(conflict: PortConflict) -> Self

Converts to this type from the input type.
