Implementations

impl CFHost

pub unsafe fn with_name( allocator: Option<&CFAllocator>, hostname: &CFString, ) -> CFRetained<CFHost>

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

pub unsafe fn with_address( allocator: Option<&CFAllocator>, addr: &CFData, ) -> CFRetained<CFHost>

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

pub unsafe fn new_copy( alloc: Option<&CFAllocator>, host: &CFHost, ) -> CFRetained<CFHost>

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

pub unsafe fn start_info_resolution( &self, info: CFHostInfoType, error: *mut CFStreamError, ) -> bool

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

Safety

error must be a valid pointer or null.

pub unsafe fn addressing( &self, has_been_resolved: *mut u8, ) -> Option<CFRetained<CFArray>>

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

Safety

has_been_resolved must be a valid pointer or null.

pub unsafe fn names( &self, has_been_resolved: *mut u8, ) -> Option<CFRetained<CFArray>>

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

Safety

has_been_resolved must be a valid pointer or null.

pub unsafe fn reachability( &self, has_been_resolved: *mut u8, ) -> Option<CFRetained<CFData>>

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

Safety

has_been_resolved must be a valid pointer or null.

pub unsafe fn cancel_info_resolution(&self, info: CFHostInfoType)

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

pub unsafe fn set_client( &self, client_cb: CFHostClientCallBack, client_context: *mut CFHostClientContext, ) -> bool

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

Safety

• client_cb must be implemented correctly.
• client_context must be a valid pointer or null.

pub unsafe fn schedule_with_run_loop( &self, run_loop: &CFRunLoop, run_loop_mode: &CFString, )

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

Safety

run_loop possibly has additional threading requirements.

pub unsafe fn unschedule_from_run_loop( &self, run_loop: &CFRunLoop, run_loop_mode: &CFString, )

👎Deprecated:

Use Network framework instead, see deprecation notice in <CFNetwork/CFHost.h>

Safety

run_loop possibly has additional threading requirements.

Methods from Deref<Target = CFType>

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: ConcreteType,

Attempt to downcast the type to that of type T.

This is the reference-variant. Use CFRetained::downcast if you want to convert a retained type. See also ConcreteType for more details on which types support being converted to.

pub fn retain_count(&self) -> usize

Get the reference count of the object.

This function may be useful for debugging. You normally do not use this function otherwise.

Beware that some things (like CFNumbers, small CFStrings etc.) may not have a normal retain count for optimization purposes, and can return usize::MAX in that case.
