Struct RetryScope 

pub struct RetryScope { /* private fields */ }

RAII scope that attributes every backoff sleep recorded on this thread during its lifetime to name (a publisher or stage label). Restores the enclosing scope on drop, so nested/sequential scopes compose. Install one around each publisher’s run and around a stage’s whole retrying section, and one per fan-out worker (via RetryScope::inherit) so the worker’s backoff ends up under the same label as its parent’s.

Implementations

impl RetryScope

pub fn enter(name: impl Into<String>) -> Self

Enter a retry-attribution scope named name on the calling thread.

pub fn inherit(label: Option<String>) -> Option<Self>

Re-enter, on a fan-out worker thread, the scope its spawning thread held — the label read from current_scope before the spawn.

None (the spawning thread held no scope) installs nothing, so the worker’s backoff falls to the unattributed bucket exactly as the parent’s would have.

Trait Implementations

impl Drop for RetryScope

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
