Errors

CallciumError

Thrown on malformed or inadmissible SDK input. offset, when set, is the error's byte position in the source blob.

ValidationError

Thrown by PolicyBuilder.build when validation reports any issue.

Carries every issue the validator found. The Error.message is the first issue's message — a diagnostic summary, not a presentation contract. Consumers rendering issues to users should iterate issues directly.

PolicyViolationError

Thrown by PolicyEnforcer.enforce when calldata fails policy enforcement. Distinct from ValidationError, which signals static issues in the policy itself.

Carries the full list of structured violations (one per failed group). The Error.message is a minimal non-lossy diagnostic summary built from the first violation's structured fields — not a presentation contract. Consumers rendering violations to users should iterate violations directly.

Types

CallciumErrorCode

Machine-readable error code for structural decoding and validation failures.

Each code names one invariant. Where Solidity detects the same invariant, the code is its error name transliterated from PascalCase to SCREAMING_SNAKE_CASE. The codes under "Inputs and validation" have no counterpart: they name input a Solidity signature cannot express. OUT_OF_PHYSICAL_BOUNDS names an invariant Solidity carries twice, as the error PolicyBuilder.OutOfPhysicalBounds and as an issue code, so the name is shared with IssueCode.
