Struct ion_c_sys::decimal::IonDecimalPtr

pub struct IonDecimalPtr { /* fields omitted */ }

Smart Pointer over ION_DECIMAL to ensure that ion_decimal_free is invoked on the instance.

Implementations

impl IonDecimalPtr

pub fn try_from_i32(value: i32) -> IonCResult<Self>

Creates an ION_DECIMAL from an i32.

pub fn try_from_bigdecimal(value: &BigDecimal) -> IonCResult<Self>

Creates an ION_DECIMAL from a BigDecimal.

pub fn try_from_decquad(value: decQuad) -> IonCResult<Self>

Creates and ION_DECIMAL from a decQuad.

pub fn try_from_existing(value: ION_DECIMAL) -> IonCResult<Self>

Binds an existing ION_DECIMAL to a pointer.

pub fn as_mut_ptr(&mut self) -> *mut ION_DECIMAL

Returns the underlying ION_DECIMAL as a mutable pointer.

Methods from Deref<Target = ION_DECIMAL>

pub fn try_assign_bigdecimal(&mut self, value: &BigDecimal) -> IonCResult<()>

Assigns a BigDecimal into this ION_DECIMAL.

pub fn try_to_bigdecimal(&mut self) -> IonCResult<BigDecimal>

Converts this ION_DECIMAL to a BigDecimal.

Special decimal values such as NaN and infinity are not supported for conversion.

This implementation borrows mutably, to avoid a copy of the underlying decimal implementation, but does not change the value.

Specifically, this code scales from/to the exponent the value to extract the coefficient.

Trait Implementations

impl DerefMut for IonDecimalPtr

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Drop for IonDecimalPtr

fn drop(&mut self)
