Struct Talck 

pub struct Talck<R, O>
where
    R: RawMutex,
    O: OomHandler,
{ /* private fields */ }

Talc lock, contains a mutex-locked Talc.

Example

let talc = Talc::new(ErrOnOom);
let talck = talc.lock::<spin::Mutex<()>>();

Implementations

impl<R, O> Talck<R, O>

where R: RawMutex, O: OomHandler,

pub const fn new(talc: Talc<O>) -> Talck<R, O>

Create a new Talck.

pub fn lock(&self) -> MutexGuard<'_, R, Talc<O>>

Lock the mutex and access the inner Talc.

pub fn try_lock(&self) -> Option<MutexGuard<'_, R, Talc<O>>>

Try to lock the mutex and access the inner Talc.

pub fn into_inner(self) -> Talc<O>

Retrieve the inner Talc.

Trait Implementations

impl<R, O> Allocator for Talck<R, O>

where R: RawMutex, O: OomHandler,

Available on crate features allocator or allocator-api2 only.

fn allocate(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

Attempts to allocate a block of memory.

unsafe fn deallocate(&self, ptr: NonNull<u8>, layout: Layout)

Deallocates the memory referenced by ptr.

unsafe fn grow( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Attempts to extend the memory block.

unsafe fn grow_zeroed( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

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

unsafe fn shrink( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Attempts to shrink the memory block.

fn allocate_zeroed(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

Behaves like allocate, but also ensures that the returned memory is zero-initialized.

fn by_ref(&self) -> &Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Allocator.

impl<R, O> Debug for Talck<R, O>

where R: Debug + RawMutex, O: Debug + OomHandler,

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

Formats the value using the given formatter.

impl<R, O> GlobalAlloc for Talck<R, O>

where R: RawMutex, O: OomHandler,

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 realloc( &self, ptr: *mut u8, old_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.

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.
