Module error 

Error types for codlet-core.

This is the internal error layer (RFC-012/021): structured, useful for developers and operators, and safe to log because no variant carries a plaintext secret. The public, enumeration-resistant error layer (PublicAuthFailure) is introduced with the redemption flow (RFC-012) once the store traits exist.

Structs

RandomError

Randomness could not be obtained. Generation fails closed on this error; codlet never substitutes a deterministic value (INV-3, SR-29-adjacent).

Enums

CodeInputError

Rejection of user-supplied code input during validation (RFC-003 FR-2).

KeyError

A key provider could not supply usable key material.

PolicyError

A crate::code::CodePolicy was constructed with an impossible or unsafe shape (RFC-003 §11.1).

PublicFormError

Public-safe form-token / CSRF failure (RFC-012, RFC-021).

PublicRedemptionError

Public-safe redemption failure (RFC-012 §4, RFC-021).

PublicSessionError

Public-safe session failure (RFC-012, RFC-021).

RedemptionFailReason

Internal reason a code redemption failed. Rich enough for logs and metrics; never shown to the user (INV-8, RFC-012 §10.1).
