[][src]Struct core_foundation::error::CFError

pub struct CFError(_);

An error value.

Methods

impl CFError[src]

pub fn domain(&self) -> CFString[src]

Returns a string identifying the domain with which this error is associated.

pub fn code(&self) -> CFIndex[src]

Returns the code identifying this type of error.

pub fn description(&self) -> CFString[src]

Returns a human-presentable description of the error.

Trait Implementations

impl ConcreteCFType for CFError[src]

impl TCFType for CFError[src]

type Ref = CFErrorRef

The reference type wrapped inside this type.

fn as_CFType(&self) -> CFType[src]

Returns the object as a wrapped CFType. The reference count is incremented by one.

fn into_CFType(self) -> CFType where
    Self: Sized
[src]

Returns the object as a wrapped CFType. Consumes self and avoids changing the reference count. Read more

fn retain_count(&self) -> CFIndex[src]

Returns the reference count of the object. It is unwise to do anything other than test whether the return value of this method is greater than zero. Read more

fn type_of(&self) -> CFTypeID[src]

Returns the type ID of this object.

fn show(&self)[src]

Writes a debugging version of this object on standard error.

fn instance_of<OtherCFType: TCFType>(&self) -> bool[src]

Returns true if this value is an instance of another type.
