Struct phper_alloc::EBox

source ·
pub struct EBox<T> { /* private fields */ }
Expand description

The Box which use php emalloc and efree to manage memory.

TODO Now feature allocator_api is still unstable, implement myself, use Box<T, Alloc> later.

Implementations§

source§

impl<T> EBox<T>

source

pub fn new(x: T) -> Self

Allocates heap memory using emalloc then places x into it.

Panic

Panic if size_of::<T>() equals zero.

source

pub unsafe fn from_raw(raw: *mut T) -> Self

Constructs from a raw pointer.

Safety

Make sure the pointer is from into_raw, or created from emalloc.

source

pub fn into_raw(b: EBox<T>) -> *mut T

Consumes and returning a wrapped raw pointer.

Will leak memory.

source

pub fn into_inner(self) -> T

Consumes the EBox, returning the wrapped value.
