Struct Jemalloc 

pub struct Jemalloc { /* private fields */ }

The allocator; install it with #[global_allocator]:

use stoolap_jemalloc::Jemalloc;

#[global_allocator]
static GLOBAL: Jemalloc = Jemalloc::new();

Implementations

impl Jemalloc

pub const fn new() -> Self

The allocator, with heap profiling off until prof::activate()

pub const fn with_profiling(self) -> Self

The allocator with heap profiling on from the process’s first allocation, as jemalloc’s prof:true,prof_active:true options set it, without a call to prof::activate(). prof::deactivate() still stops it.

Trait Implementations

impl Clone for Jemalloc

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Jemalloc

impl Debug for Jemalloc

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

Formats the value using the given formatter.

impl Default for Jemalloc

fn default() -> Self

Returns the “default value” for a type.

impl GlobalAlloc for Jemalloc

unsafe fn alloc(&self, layout: Layout) -> *mut u8

Allocates memory as described by the given layout.

unsafe fn dealloc(&self, ptr: *mut u8, layout: Layout)

Deallocates the block of memory at the given ptr pointer with the given layout.

unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8

Behaves like alloc, but also ensures that the contents are set to zero before being returned.

unsafe fn realloc( &self, ptr: *mut u8, layout: Layout, new_size: usize, ) -> *mut u8

Shrinks or grows a block of memory to the given new_size in bytes. The block is described by the given ptr pointer and layout.
