Enum IntentKind 

#[repr(i32)]
pub enum IntentKind {
    SendMessage = 1,
    KeyUpdate = 2,
    MetadataUpdate = 3,
    UpdateGroupMembership = 4,
    UpdateAdminList = 5,
    UpdatePermission = 6,
    ReaddInstallations = 7,
    ProposeMemberUpdate = 8,

Variants

SendMessage = 1

KeyUpdate = 2

MetadataUpdate = 3

UpdateGroupMembership = 4

UpdateAdminList = 5

UpdatePermission = 6

ReaddInstallations = 7

ProposeMemberUpdate = 8

ProposeGroupContextExtensions = 9

CommitPendingProposals = 10

BootstrapMigration = 11

One-time bootstrap commit that flips a group from the legacy GroupContextExtensions-backed metadata layout onto the AppData dictionary. Distinct from Self::ProposeGroupContextExtensions because the payload shape is different (it bundles a GCE proposal with a fan-out of AppDataUpdate proposals) and because the dispatch path in mls_sync needs an explicit marker rather than sniffing the extension-set shape.

AppDataUpdate = 12

Generic AppData component write. The intent payload carries a (component_id, AppDataUpdateOp) pair where AppDataUpdateOp is either Replace(bytes) (full-replace components — Bytes / String types) or DeltaWithBase { pre, post } (TlsMap / TlsSet types, where the handler computes the residual delta at commit time from the current state, the pre value, and the post value).

Replaces the proliferation of per-component IntentKinds. Existing typed intents (UpdateAdminList, UpdatePermission, MetadataUpdate) are not migrated by the introducing PR — they continue to work, and a follow-on can fold them in.

Implementations

impl IntentKind

pub fn all() -> impl Iterator<Item = IntentKind>

Every kind this build knows how to deserialize, as a lazy iterator — collect into a Vec only where a filter needs one. Production queries pass these as the allowed_kinds filter so rows written by a NEWER build (which may use discriminants this build has no variant for) are excluded in SQL instead of poisoning the whole load() — FromSql errors on unknown discriminants, and one such row would otherwise wedge every intent query for the group after an app downgrade. Unknown-kind rows stay untouched in the table and resume processing when the app is upgraded again.

Exhaustive by construction: strum::EnumIter generates the iteration over every variant, so a newly added IntentKind is included automatically — which is exactly right here, since every variant is, by definition, a kind this build can deserialize.

impl FromSql<Integer, Sqlite> for IntentKind

where i32: FromSql<Integer, Sqlite>,

fn from_sql(bytes: <Sqlite as Backend>::RawValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql( bytes: Option<<DB as Backend>::RawValue<'_>>, ) -> Result<Self, Box<dyn Error + Send + Sync>>
