Enum HistoryPropagationScope 

pub enum HistoryPropagationScope {
    OwnHistory,
    Lineage,
}

Controls how history flows from a calling workflow into a scheduled activity or child workflow.

Mirrors the proto HistoryPropagationScope enum without exposing the raw i32 discriminants. The default None scope is intentionally not part of the public surface — callers either pass an explicit scope or omit the option entirely (which is equivalent to “no propagation”).

Variants

OwnHistory

Forward only the caller’s own history events. Ancestral history (anything the caller itself received from its parent) is dropped at this trust boundary.

Lineage

Forward the caller’s own history events and the full ancestor chain. Any propagated history the caller received is forwarded as additional chunks alongside the caller’s own.

Trait Implementations

impl Clone for HistoryPropagationScope

fn clone(&self) -> HistoryPropagationScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistoryPropagationScope

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

Formats the value using the given formatter.

impl From<HistoryPropagationScope> for HistoryPropagationScope

fn from(scope: HistoryPropagationScope) -> Self

Converts to this type from the input type.

impl Hash for HistoryPropagationScope

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 HistoryPropagationScope

fn eq(&self, other: &HistoryPropagationScope) -> 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 TryFrom<HistoryPropagationScope> for HistoryPropagationScope

type Error = ()

The type returned in the event of a conversion error.

fn try_from(scope: HistoryPropagationScope) -> Result<Self, Self::Error>

Performs the conversion.
