Function jemalloc_ctl::stats::mapped

pub fn mapped() -> Result<usize>

Returns the total number of bytes in active extents mapped by the allocator.

This does not include inactive extents, even those taht contain unused dirty pages, so there is no strict ordering between this and the value returned by resident. This is a multiple of the page size, and is larger than the value returned by active.

This statistic is cached, and is only refreshed when the epoch is advanced. See the epoch type for more information.

This corresponds to stats.mapped in jemalloc's API.

Examples

jemalloc_ctl::epoch().unwrap();
println!("{} bytes of total mapped data", jemalloc_ctl::stats::mapped().unwrap());
