Struct CoalescingStats 

pub struct CoalescingStats {
    pub original_requests: usize,
    pub coalesced_requests: usize,
    pub bytes_fetched: u64,
    pub bytes_needed: u64,
    pub overhead_bytes: u64,
}

Statistics describing the efficiency of a coalescing operation.

Fields

original_requests: usize

Number of original (pre-coalescing) range requests.

coalesced_requests: usize

Number of coalesced (post-coalescing) fetch requests.

bytes_fetched: u64

Total bytes that will be fetched (including gap fill-in).

bytes_needed: u64

Total bytes actually needed (sum of original range lengths).

overhead_bytes: u64

Bytes fetched that are not part of any original range.

Implementations

impl CoalescingStats

pub fn overhead_ratio(&self) -> f64

Fraction of fetched bytes that are overhead (0.0 = no overhead).

pub fn request_reduction(&self) -> f64

Fraction by which the request count was reduced (0.0 = no reduction, 1.0 = all merged into one).

Trait Implementations

impl Clone for CoalescingStats

fn clone(&self) -> CoalescingStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoalescingStats

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

Formats the value using the given formatter.

impl Default for CoalescingStats

fn default() -> CoalescingStats

Returns the “default value” for a type.
