Struct AdapterContext 

pub struct AdapterContext { /* private fields */ }

A caller-supplied witness and logical operation identity.

Clone this context for retries of the same operation. Create a new context with a distinct identity for a different call, including identical parallel requests. Identity is execution-local; it does not assert replay equivalence. This handle is runtime-only and must never be serialized into provider data.

Implementations

impl AdapterContext

pub fn operation(&self) -> &str

Caller-owned identity of this logical operation within the execution.

pub fn new( sink: Arc<dyn Witness + Send + Sync>, subject: Subject, operation: impl Into<String>, ) -> Self

Bind a logical operation to its witness and existing subject. The caller must use a non-sensitive, execution-unique operation identity.

pub fn for_host_attempt(&self, subject: Subject, attempt: NonZeroU64) -> Self

Bind an explicit host attempt to its current dispatch subject.

The logical operation, witness and HTTP send counter remain shared. Existing clones retain their own subject and host ordinal, so an older in-flight attempt cannot be relabeled by a concurrent retry. The host owns ordinal allocation and must start a new context for a changed logical request rather than reusing this operation identity.
