Struct stats_alloc::StatsAlloc

source · [−]

pub struct StatsAlloc<T: GlobalAlloc> { /* private fields */ }

Expand description

An instrumenting middleware which keeps track of allocation, deallocation, and reallocation requests to the underlying global allocator.

Implementations

source

impl StatsAlloc<System>

source

pub const fn system() -> Self

Provides access to an instrumented instance of the system allocator.

source

impl<T: GlobalAlloc> StatsAlloc<T>

source

pub const fn new(inner: T) -> Self

Provides access to an instrumented instance of the given global allocator.

source

pub fn stats(&self) -> Stats

Takes a snapshot of the current view of the allocator statistics.
