Struct fdb_rl::scan::TimeScanLimiter

pub struct TimeScanLimiter {
    limiter_mode: TimeLimiterMode,
    start_instant: Option<Instant>,
    time_limit_duration: Option<Duration>,
}

Track time remaining until a given time limit, after which scans should not be allowed.

Fields

limiter_mode: TimeLimiterMode

start_instant: Option<Instant>

time_limit_duration: Option<Duration>

Implementations

impl TimeScanLimiter

pub fn new(time_limit: u64) -> TimeScanLimiter

Create a TimeScanLimiter with time_limit specified in milliseconds.

pub fn unlimited() -> TimeScanLimiter

Create an unlimited TimeScanLimiter

pub(crate) fn try_keyvalue_scan(&self) -> bool

Return true if keyvalue can be read otherwise return false.

Used by LimitManager::try_keyvalue_scan (Linking does not work!).

Trait Implementations

impl Clone for TimeScanLimiter

fn clone(&self) -> TimeScanLimiter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimeScanLimiter

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

Formats the value using the given formatter.

impl PartialEq<TimeScanLimiter> for TimeScanLimiter

fn eq(&self, other: &TimeScanLimiter) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
