Member Function Documentation

◆ allocate_8()

template<class Resource >

template<class T >

T* ArenaResource< Resource >::allocate_8 ( size_t n_items )

inline

Allocate and return data pointer of n_item array of type T (alignment to length 8 bytes)

Definition at line 103 of file arena_resource.hh.

◆ allocate_simd()

template<class Resource >

template<class T >

T* ArenaResource< Resource >::allocate_simd ( size_t n_items )

inline

Allocate and return data pointer of n_item array of type T (alignment to length given by simd_alignment constructor argument)

Definition at line 110 of file arena_resource.hh.

Here is the caller graph for this function:

◆ do_allocate()

template<class Resource >

void* ArenaResource< Resource >::do_allocate	(	size_t	bytes,
		size_t	alignment
	)

inlineoverrideprotected

Override do_allocate to handle allocation logic.

Definition at line 141 of file arena_resource.hh.

◆ do_deallocate()

template<class Resource >

void ArenaResource< Resource >::do_deallocate	(	FMT_UNUSED void *	p,
		FMT_UNUSED size_t	bytes,

	)

inlineoverrideprotected

Override do_deallocate (no-op for monotonic buffer)

Definition at line 146 of file arena_resource.hh.

◆ do_is_equal()

template<class Resource >

bool ArenaResource< Resource >::do_is_equal ( const std::pmr::memory_resource & other ) const

inlineoverrideprotectednoexcept
