Enum FactorizationError 

pub enum FactorizationError {

}

Errors raised while building or validating a FactorizedSchema.

These replace the previous assert!-based invariant checks so a malformed plan surfaces as a query error instead of aborting the server process. See AGENTS.md: “Never use unwrap”.

Variants

TooManyUnflatGroups(usize)

More than one group is left unflat at the same nesting level.

GroupExpectedFlat(FGroupPos)

A group that was expected to be flat is still unflat.

GroupPosOutOfRange(FGroupPos)

A group position passed to a flatten/set operation is out of range.

ExpressionAlreadyInScope(ExpressionId)

An expression was inserted into scope more than once.

ExpressionAlreadyMapped(ExpressionId)

An expression was mapped to a group more than once.

DuplicateExpressionId(ExpressionId)

A duplicate expression id was registered inside a group.

DuplicateExpressionName(String)

A duplicate expression name was registered inside a group.

InvalidFlattenPos(FGroupPos)

flatten_group was given an invalid group position.

InvalidSingleStatePos(FGroupPos)

set_group_as_single_state was given an invalid group position.

GroupAlreadyFlat

set_flat was called on a group that is already flat.

GroupAlreadySingleState

set_single_state was called on a group that is already single-state.

EmptyGroupPositions

A group position set passed to a leader/validator was empty.

NonEmptyGroupPositions

A non-empty group position set was required but found empty.

Trait Implementations

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
