Struct TrellisError 

pub struct TrellisError<O, E> {
    pub error: E,
    pub result: Option<O>,
}

Error returned when engine execution fails during procedure execution.

This error wraps:

• the underlying procedure error (E)
• optionally a partial output (O) representing the last known state

This is useful for partial recovery scenarios where:

• execution failed mid-run
• but the solver state is still meaningful

Fields

error: E

result: Option<O>

Optional partial result produced before failure.

Trait Implementations

impl<O: Debug, E: Debug> Debug for TrellisError<O, E>

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

Formats the value using the given formatter.

impl<O, E: Debug> Display for TrellisError<O, E>

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

Formats the value using the given formatter.

impl<O, E> Error for TrellisError<O, E>

where E: Error + 'static, Self: Debug + Display,

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>)
