Implementations

impl ObserverError

pub fn log(self) -> Self

Log the error with tracing::error and return self for chaining

This method allows for a consistent error logging pattern throughout the observers module, ensuring all errors are properly recorded.

Example

operation()
    .map_err(|e| e.log())?;

pub fn log_with_source<E: Debug>(self, source_error: E) -> Self

Log the error with the original source error from a third-party library

This method logs both the ObserverError and the underlying error from external libraries (e.g., Rerun’s errors). This provides full debugging context when errors occur in third-party code.

Arguments

• source_error - The original error from the third-party library (must implement Debug)

Example

rec_log()
    .map_err(|e| {
        ObserverError::LoggingFailed {
            entity_path: "world/points".to_string(),
            reason: format!("{}", e)
        }
        .log_with_source(e)
    })?;

Trait Implementations

impl Clone for ObserverError

fn clone(&self) -> ObserverError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObserverError

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

Formats the value using the given formatter.

impl Display for ObserverError

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

Formats the value using the given formatter.

impl Error for ObserverError

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<ObserverError> for ApexSolverError

fn from(source: ObserverError) -> Self

Converts to this type from the input type.
