Struct polars_utils::sync::SyncPtr

source · 
pub struct SyncPtr<T>(/* private fields */);
Expand description

Utility that allows use to send pointers to another thread. This is better than going through usize as MIRI can follow these.

Implementations§

source§

impl<T> SyncPtr<T>

source

pub unsafe fn new(ptr: *mut T) -> Self

§Safety

This will make a pointer sync and send. Ensure that you don’t break aliasing rules.

source

pub unsafe fn from_const(ptr: *const T) -> Self

§Safety

This will make a pointer sync and send. Ensure that you don’t break aliasing rules.

source

pub fn new_null() -> Self

source

pub fn get(&self) -> *mut T

source

pub fn is_null(&self) -> bool

source

pub unsafe fn deref_unchecked(&self) -> &'static T

§Safety

Derefs a raw pointer, no guarantees whatsoever.
