SparseSyscallHistogram

detcore_model::syscall_histogram

Struct SparseSyscallHistogram 

Source 
pub struct SparseSyscallHistogram { /* private fields */ }
Expand description

A finished thread’s histogram: only its nonzero slots, (number, counts) by ascending number.

A thread counts into a dense SyscallHistogram, which costs a fixed 14,784 bytes; a thread that has exited reports this form instead, so the scheduler keeps a few hundred bytes per finished thread rather than the whole array (a 4,000-thread run kept 59 MB of dense arrays). The run’s total is summed back into one dense histogram (SparseSyscallHistogram::add_to).

Implementations§

Source§

impl SparseSyscallHistogram

Source

pub fn merge(&mut self, other: &SparseSyscallHistogram)

Add every count of other to this histogram, keeping number order.

Source

pub fn add_to(&self, total: &mut SyscallHistogram)

Add every count of this histogram to the dense total. A number outside the pinned table, which no SyscallHistogram can produce, is skipped.

Source

pub fn total_calls(&self) -> u64

Total entries over every syscall.
