Struct VerifyPoll 

pub struct VerifyPoll<'a> {
    pub expected_basename: &'a str,
    pub previous_basename: Option<&'a str>,
    pub interval: Duration,
    pub budget: Duration,
}

previous_basename = Some(p) enables hard-mismatch detection: any third basename -> FlippedToUnexpected immediately. Rollback path leaves it None (no meaningful pre-state). Read errors during polling are non-fatal.

Fields

expected_basename: &'a str

previous_basename: Option<&'a str>

interval: Duration

budget: Duration

Implementations

impl<'a> VerifyPoll<'a>

pub fn new(expected_basename: &'a str) -> Self

pub fn with_previous(self, previous: &'a str) -> Self

pub async fn until_settled(&self) -> PollOutcome

Pure: no logging, deterministic timing.
