Enum HostRolloutState 

pub enum HostRolloutState {
    Pending,
    Activating,
    Deferred,
    Soaking,
    Converged,
    Failed,
    Reverted,
}

7-state machine per RFC-0005 §3. Deferred covers the “activation staged but live-switch skipped pending operator reboot” case (critical-component swap; see RFC-0005 §3.5).

Variants

Implementations

impl HostRolloutState

pub fn as_db_str(&self) -> &'static str

Canonical literal — matches the SQL CHECK on host_rollout_records.state and the RFC-0005 §3 wire shape.

pub fn from_db_str(s: &str) -> Result<Self, HostRolloutStateParseError>

pub fn is_terminal_for_ordering(&self) -> bool

Terminal-for-ordering: predecessor hosts/waves can release once every host hits this state. Converged is the canonical health-verified state; Deferred is “staged for reboot, ordering-eligible but not health-verified” — both clear host-edges + wave-promotion gates. channel_edges keeps the stricter Converged-only predicate (cross-channel cascade should wait for actual verification).

pub fn is_in_flight(&self) -> bool

Host is consuming a disruption-budget slot (still moving through activation / soak). Deferred is NOT in-flight: the in-memory activation work is done, the host is just waiting on the operator to reboot.

pub fn is_failed(&self) -> bool

Stuck and staying stuck; needs operator action.

Trait Implementations

impl Clone for HostRolloutState

fn clone(&self) -> HostRolloutState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HostRolloutState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HostRolloutState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromSql for HostRolloutState

fn column_result(value: ValueRef<'_>) -> FromSqlResult<Self>

Converts SQLite value into Rust value.

impl Hash for HostRolloutState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HostRolloutState

fn eq(&self, other: &HostRolloutState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HostRolloutState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSql for HostRolloutState

fn to_sql(&self) -> Result<ToSqlOutput<'_>>

Converts Rust value to SQLite value
