Struct rlsf::FlexTlsf[−][src]

pub struct FlexTlsf<Source: FlexSource, FLBitmap, SLBitmap, const FLLEN: usize, const SLLEN: usize> { /* fields omitted */ }
Expand description

A wrapper of Tlsf that automatically acquires fresh memory pools from FlexSource.

Implementations

impl<Source: FlexSource, FLBitmap: BinInteger, SLBitmap: BinInteger, const FLLEN: usize, const SLLEN: usize> FlexTlsf<Source, FLBitmap, SLBitmap, FLLEN, SLLEN>[src]

pub fn new(source: Source) -> Self[src]

Construct a new FlexTlsf object.

pub fn source_ref(&self) -> &Source[src]

Borrow the contained Source.

pub unsafe fn source_mut_unchecked(&mut self) -> &mut Source[src]

Mutably borrow the contained Source.

Safety

The caller must not replace the Source with another one or modify any existing allocations in the Source.

pub fn allocate(&mut self, layout: Layout) -> Option<NonNull<u8>>[src]

Attempt to allocate a block of memory.

Returns the starting address of the allocated memory block on success; None otherwise.

Time Complexity

This method will complete in constant time (assuming Source’s methods do so as well).

pub unsafe fn deallocate(&mut self, ptr: NonNull<u8>, align: usize)[src]

Deallocate a previously allocated memory block.

Time Complexity

This method will complete in constant time (assuming Source’s methods do so as well).

Safety

  • ptr must denote a memory block previously allocated via self.
  • The memory block must have been allocated with the same alignment (Layout::align) as align.

pub unsafe fn reallocate(
    &mut self,
    ptr: NonNull<u8>,
    new_layout: Layout
) -> Option<NonNull<u8>>[src]

Shrink or grow a previously allocated memory block.

Returns the new starting address of the memory block on success; None otherwise.

Time Complexity

Unlike other methods, this method will complete in linear time (O(old_size)), assuming Source’s methods do so as well.

Safety

  • ptr must denote a memory block previously allocated via self.
  • The memory block must have been allocated with the same alignment (Layout::align) as new_layout.
