Struct ErasedBorrowedPtr 

pub struct ErasedBorrowedPtr { /* private fields */ }

Implementations

impl ErasedBorrowedPtr

pub const unsafe fn from_raw(ptr: *mut c_void) -> Self

Safety

ptr must be either null or point to a valid value for the duration of any pointer-based operations performed through this wrapper.

pub const fn null() -> Self

pub const fn as_raw(&self) -> *mut c_void

pub fn is_null(&self) -> bool

pub fn with_ptr<R: Any, F>(&self, op: F) -> Result<R>

where F: FnOnce(NonNull<c_void>) -> Result<R>,

pub fn with_ptr_ok<R: Any, F>(&self, op: F) -> Result<R>

where F: FnOnce(NonNull<c_void>) -> R,
