Implementations

impl NSDecimalNumberHandler

pub fn default_decimal_number_handler() -> NSDecimalNumberHandler

Returns the default instance of NSDecimalNumberHandler.

pub fn decimal_number_handler_with_rounding_mode_scale_raise_on_exactness_raise_on_overflow_raise_on_underflow_raise_on_divide_by_zero( rounding_mode: NSRoundingMode, scale: c_short, exact: bool, overflow: bool, underflow: bool, divide_by_zero: bool, ) -> Self

Returns an NSDecimalNumberHandler object with customized behavior.

pub fn init_with_rounding_mode_scale_raise_on_exactness_raise_on_overflow_raise_on_underflow_raise_on_divide_by_zero( &mut self, rounding_mode: NSRoundingMode, scale: c_short, exact: bool, overflow: bool, underflow: bool, divide_by_zero: bool, ) -> Self

where Self: Sized + FromId,

Returns an NSDecimalNumberHandler object initialized so it behaves as specified by the method’s arguments.

Methods from Deref<Target = Object>

pub fn class(&self) -> &Class

Returns the class of self.

pub unsafe fn get_ivar<T>(&self, name: &str) -> &T

where T: Encode,

Returns a reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

pub unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut T

where T: Encode,

Returns a mutable reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

pub unsafe fn set_ivar<T>(&mut self, name: &str, value: T)

where T: Encode,

Sets the value of the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.
