The machine-readable type of a JmapError.

Known variants are the RFC 8620 request-level error types (§3.6.1, whose wire form in an RFC 7807 problem-details body is prefixed with urn:ietf:params:jmap:error:), the §3.6.2 method-level error types, and the method-specific errors of §5.1 to §5.6. Every other wire string, including extension errors such as "rateLimited", is Self::Other.

From<&str> and Deserialize share one mapping: a known wire string always builds its typed variant, never Other.

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.

UnknownCapability

RFC 8620 §3.6.1 — the request used an unsupported capability.

NotJson

RFC 8620 §3.6.1 — the content type was not application/json or the request did not parse as I-JSON.

NotRequest

RFC 8620 §3.6.1 — the request parsed as JSON but not as a Request object.

Limit

RFC 8620 §3.6.1 — the request exceeded a server limit; the limit’s name is JmapError::limit_name.

ServerUnavailable

RFC 8620 §3.6.2 — an internal server resource was temporarily unavailable.

ServerFail

RFC 8620 §3.6.2 — an unexpected error occurred.

ServerPartialFail

RFC 8620 §3.6.2 — some, but not all, expected changes were made.

UnknownMethod

RFC 8620 §3.6.2 — the server does not recognise this method name.

InvalidArguments

RFC 8620 §3.6.2 — an argument is of the wrong type or invalid.

InvalidResultReference

RFC 8620 §3.6.2 — a result reference failed to resolve.

Forbidden

RFC 8620 §3.6.2 — the method or arguments are forbidden.

AccountNotFound

RFC 8620 §3.6.2 — the accountId does not correspond to a valid account.

AccountNotSupportedByMethod

RFC 8620 §3.6.2 — the account does not support this method.

AccountReadOnly

RFC 8620 §3.6.2 — the account is read-only.

RequestTooLarge

RFC 8620 §5.1 and §5.3 — too many ids or objects in one call.

CannotCalculateChanges

RFC 8620 §5.2 and §5.6 — the server cannot calculate the changes from the given state.

StateMismatch

RFC 8620 §5.3 and §5.4 — ifInState did not match the current state.

FromAccountNotFound

RFC 8620 §5.4 — the fromAccountId does not correspond to a valid account.

FromAccountNotSupportedByMethod

RFC 8620 §5.4 — the fromAccountId account does not support this method.

AnchorNotFound

RFC 8620 §5.5 — the anchor was not found in the results.

UnsupportedSort

RFC 8620 §5.5 — the sort is syntactically valid but unsupported.

UnsupportedFilter

RFC 8620 §5.5 — the filter is syntactically valid but unsupported.

TooManyChanges

RFC 8620 §5.6 — there are more changes than maxChanges.

Other(String)

Any other error type, such as an extension’s.
