Struct charts::data::Data

pub struct Data { /* private fields */ }

Structures that aggregates all the information about the allocations so far.

Implementations

impl Data

pub fn new() -> Self

Constructor.

pub fn reserve(&mut self, capa: usize)

Reserves space for the Alloc vector.

pub fn mark_timestamp(&mut self, ts: SinceStart)

Marks a timestamp.

This sets the current time to the input timestamp.

pub fn init(&self) -> Option<&Init>

Init accessor.

pub fn has_init(&self) -> bool

True if the data is initialized.

pub fn alloc_count(&self) -> usize

Total number of allocations.

pub fn get_stats() -> Res<Option<AllocStats>>

Allocation statistics stored in the global data.

pub fn stats(&self) -> Option<AllocStats>

Allocation statistics.

pub fn current_time(&self) -> &SinceStart

Current time accessor.

pub fn start_time(&self) -> Res<Date>

Time at which the profiling run started.

pub fn get_alloc(&self, uid: Alloc) -> Option<&Alloc>

Alloc accessor.

Fails if the UID is unknown.

pub fn iter_allocs(&self) -> impl Iterator<Item = &Alloc>

Iterates over all the allocations.

pub fn has_new_stuff_since(&self, time: Option<(Alloc, SinceStart)>) -> bool

True if there are any new events since some timestamp.

pub fn last_events(&self) -> Option<(Alloc, SinceStart)>

Yields the last events at the current time.

pub fn iter_new_events<'me>(
    &'me self,
    since: Option<(Alloc, SinceStart)>,
    action: impl FnMut(Either<&'me Alloc, (SinceStart, &'me Alloc)>) -> Res<bool>
) -> Res<()>

Iterates over the new (de)allocation events in chronological order.

Argument since is an optional pair containing an allocation UID, and a time-of-death (TOD). Input action will run on all new allocations since the UID (exclusive), and all the deallocations since the TOD (exclusive).

Input function action returns a boolean indicating whether the iteration should continue.

impl Data

Mutable Functions

pub fn stats_do(&mut self, action: impl FnOnce(&mut AllocStats))

Applies some action on the allocation statistics.

pub fn fill_stats(&mut self) -> Res<()>

Fills the allocation statistics.

pub fn reset(&mut self, dump_dir: impl Into<PathBuf>, init: Init)

Resets the data.

Called when the init file of a run has changed.

pub fn build_new(&mut self, alloc: Builder) -> Res<()>

Builds a new allocation.

pub fn add_new(&mut self, alloc: Alloc) -> Res<()>

Registers a new allocation.

pub fn add_dead(&mut self, timestamp: SinceStart, uid: Alloc) -> Res<()>

Registers an allocation’s death.

pub fn add_diff(&mut self, diff: Diff) -> Res<()>

Registers a diff.

Trait Implementations

impl Index<Alloc> for Data

type Output = Alloc

The returned type after indexing.

fn index(&self, uid: Alloc) -> &Alloc

Performs the indexing (container[index]) operation.
