Enum SignatureCheckMode 

pub enum SignatureCheckMode {
    Strict,
    Relaxed,
}

Controls how strictly workflow signatures are validated on resume.

The workflow signature encodes the persisted contract (step keys, wait keys, timeout, and input/output type names). By default (Strict) a mismatch between the signature stored on the run and the signature compiled into the current binary blocks the run with BlockedSignatureMismatch.

During a rolling deploy, all nodes run the same source version but the new binary may carry a different signature if any tracked field changed — even when the change is safe to resume through. Setting signature_check = "relaxed" in [workflow] tells the runtime to accept any registered handler for the matching (name, version) pair and skip the hash comparison, preventing stranded runs during the transition window.

Switch back to "strict" once all nodes are on the new binary.

Variants

Strict

Require an exact signature match before resuming a run (default).

Relaxed

Accept any handler registered for the matching (name, version) pair, ignoring the signature hash. Use during rolling deploys.

Trait Implementations

impl Clone for SignatureCheckMode

fn clone(&self) -> SignatureCheckMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureCheckMode

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

Formats the value using the given formatter.

impl Default for SignatureCheckMode

fn default() -> SignatureCheckMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SignatureCheckMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SignatureCheckMode

fn eq(&self, other: &SignatureCheckMode) -> 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 SignatureCheckMode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
