Enum PlanCacheError 

#[non_exhaustive]
pub enum PlanCacheError {
    Database(SqlxError),
    Serialization(Error),
    Extraction(String),
}

Error type for plan cache operations.

All errors are non-fatal in the context of the planning critical path: callers should log the error and fall back to full LLM decomposition.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Database(SqlxError)

A SQLite query failed.

Serialization(Error)

JSON serialization or deserialization of a plan template failed.

Extraction(String)

Extracting a PlanTemplate from a completed TaskGraph failed.

Trait Implementations

impl Debug for PlanCacheError

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

Formats the value using the given formatter.

impl Display for PlanCacheError

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

Formats the value using the given formatter.

impl Error for PlanCacheError

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.
