Struct puffin::ThreadProfiler

pub struct ThreadProfiler { /* private fields */ }

Collects profiling data for one thread

Implementations

impl ThreadProfiler

pub fn initialize(
    now_ns: fn() -> NanoSecond,
    reporter: fn(_: ThreadInfo, _: &StreamInfoRef<'_>)
)

Explicit initialize with custom callbacks.

If not called, each thread will use the default nanosecond source (now_ns()) and report scopes to the global profiler (global_reporter()).

For instance, when compiling for WASM the default timing function (now_ns()) won’t work, so you’ll want to call puffin::ThreadProfiler::initialize(my_timing_function, puffin::global_reporter);.

pub fn begin_scope(&mut self, id: &str, location: &str, data: &str) -> usize

Returns position where to write scope size once the scope is closed.

pub fn end_scope(&mut self, start_offset: usize)

pub fn call<R>(f: impl Fn(&mut Self) -> R) -> R

Do something with the thread local ThreadProfiler

Trait Implementations

impl Default for ThreadProfiler

fn default() -> Self

Returns the “default value” for a type.
