Struct DropCounts 

Source 
pub struct DropCounts<Reason> { /* private fields */ }
Expand description

Fixed-capacity aggregate counters keyed by a caller’s drop taxonomy.

Implementations§

Source§

impl<Reason: DropReason> DropCounts<Reason>

Source

pub fn count(&self, reason: Reason) -> Option<usize>

Count drops for one reason.

Returns None when reason is not a declared member of the closed taxonomy used to construct this result.

Source

pub fn total(&self) -> usize

Count all drops.
