Struct allocation_counter::AllocationInfo

pub struct AllocationInfo {
    pub count_total: u64,
    pub count_current: i64,
    pub count_max: u64,
    pub bytes_total: u64,
    pub bytes_current: i64,
    pub bytes_max: u64,
}

The allocation information obtained by a measure() call.

Fields

count_total: u64

The total number of allocations made during a measure() call.

count_current: i64

The current (net result) number of allocations during a measure() call.

A non-zero value of this field means that the function did not deallocate all allocations, as shown below.

let info = allocation_counter::measure(|| {
    let b = std::hint::black_box(Box::new(1_u32));
    std::mem::forget(b);
});
assert_eq!(info.count_current, 1);

count_max: u64

The max number of allocations held during a point in time during a measure() call.

bytes_total: u64

The total amount of bytes allocated during a measure() call.

bytes_current: i64

The current (net result) amount of bytes allocated during a measure() call.

A non-zero value of this field means that not all memory was deallocated, as shown below.

let info = allocation_counter::measure(|| {
    let b = std::hint::black_box(Box::new(1_u32));
    std::mem::forget(b);
});
assert_eq!(info.bytes_current, 4);

bytes_max: u64

The max amount of bytes allocated at one time during a measure() call.

Trait Implementations

impl AddAssign<AllocationInfo> for AllocationInfo

fn add_assign(&mut self, other: Self)

Performs the += operation.

impl Clone for AllocationInfo

fn clone(&self) -> AllocationInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AllocationInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AllocationInfo

fn default() -> AllocationInfo

Returns the “default value” for a type.

impl Hash for AllocationInfo

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<AllocationInfo> for AllocationInfo

fn eq(&self, other: &AllocationInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
