Struct SentTracker 

pub struct SentTracker(/* private fields */);

Whether request bytes may have left the process. Clones share state.

Implementations

impl SentTracker

pub fn new() -> Self

pub fn begin_write(&self) -> bool

Called before a request byte is written. False once aborted: the write must not happen.

pub fn try_abort(&self) -> bool

Forbid every future write. True if no write ever began, so no request byte left the process and none will; false if one may have.

pub fn is_aborted(&self) -> bool

True once Self::try_abort won: no request byte ever left.

pub fn may_have_sent(&self) -> bool

True once a write began: request bytes may have left the process. Conservative: a write that began counts even if it failed.

pub fn bytes(&self) -> u64

Bytes the tracked layer accepted for sending.
