Module backend 

Shared backend infrastructure for all JMAP server crates.

Re-exports the marker traits from jmap-types and adds the result types, BackendChangesError, and JmapBackend supertrait. Domain crates add their write-side methods and domain-specific error variants on top.

Structs

AddedItem

One entry in the added list of a /queryChanges response (RFC 8620 §5.6).

ChangesResult

Result of a /changes call (RFC 8620 §5.2).

QueryChangesResult

Result of a /queryChanges call (RFC 8620 §5.6).

QueryResult

Result of a /query call (RFC 8620 §5.5).

ReservedExtrasKey

Returned by SetError::validate_extras when SetError::extra contains a key that collides with a typed-field wire-name in RESERVED_SET_ERROR_WIRE_NAMES (bd:JMAP-jfia.17).

SetError

A per-item error in a /set response (notCreated, notUpdated, notDestroyed maps) (RFC 8620 §5.3).

Enums

BackendChangesError

Error type returned by JmapBackend::get_changes and JmapBackend::query_changes.

BackendSetError

Error type returned by create/update/destroy backend methods.

SetErrorType

The machine-readable type for a SetError (RFC 8620 §5.3 and RFC 8621).

Constants

RESERVED_SET_ERROR_WIRE_NAMES

Reserved wire-name keys that SetError::with_extra MUST NOT receive.

Traits

GetObject

Marker for object types that support get and changes operations.

JmapBackend

Read-side backend supertrait shared by all JMAP server crates.

JmapObject

Marker trait for all JMAP object types.

QueryObject

Marker for object types that support query and queryChanges operations.

SetObject

Marker for object types that support set (create/update/destroy) operations.
