Struct fdb_rl::scan::ScanLimiter

pub struct ScanLimiter {
    keyvalue_scan_limiter: Option<KeyValueScanLimiter>,
    byte_scan_limiter: Option<ByteScanLimiter>,
    time_scan_limiter: Option<TimeScanLimiter>,
}

An encapsulation of the out-of-band state of scan execution.

Key-value limit, byte limit, time limit, are considered out-of-band states.

Fields

keyvalue_scan_limiter: Option<KeyValueScanLimiter>

byte_scan_limiter: Option<ByteScanLimiter>

time_scan_limiter: Option<TimeScanLimiter>

Implementations

impl ScanLimiter

pub fn new( keyvalue_scan_limiter: Option<KeyValueScanLimiter>, byte_scan_limiter: Option<ByteScanLimiter>, time_scan_limiter: Option<TimeScanLimiter> ) -> ScanLimiter

Creates an execute state with a supplied set of resource limiters.

pub fn into_parts( self ) -> (Option<KeyValueScanLimiter>, Option<ByteScanLimiter>, Option<TimeScanLimiter>)

If present, extract KeyValueScanLimiter, ByteScanLimiter, TimeScanLimiter from ScanLimiter.

pub fn get_keyvalue_scan_limiter_ref(&self) -> Option<&KeyValueScanLimiter>

Get reference to KeyValueScanLimiter if one is present.

pub fn get_byte_scan_limiter_ref(&self) -> Option<&ByteScanLimiter>

Get reference to ByteScanLimiter if one is present.

pub fn get_time_scan_limiter_ref(&self) -> Option<&TimeScanLimiter>

Get reference to TimeScanLimiter if one is present.
