Struct dec::Status

pub struct Status { /* fields omitted */ }

Represents exceptional conditions resulting from operations on decimal numbers.

For details about the various exceptional conditions, consult the Exceptional Conditions chapter of the General Decimal Arithmetic specification.

Implementations

impl Status

pub fn any(&self) -> bool

Reports whether any of the condition flags are set.

pub fn conversion_syntax(&self) -> bool

Reports whether the conversion syntax flag is set.

Operations set this flag when an invalid string is converted to a decimal.

pub fn division_by_zero(&self) -> bool

Reports whether the division by zero flag is set.

Operations set this flag when a nonzero dividend is divided by zero.

pub fn division_impossible(&self) -> bool

Reports whether the division impossible flag is set.

Operations set this flag if the integer result of a division had too many digits.

pub fn division_undefined(&self) -> bool

Reports whether the division undefined flag is set.

Operations set this flag when a zero dividend is divided by zero.

pub fn insufficient_storage(&self) -> bool

Reports whether the insufficient storage flag is set.

Operations set this flag if memory allocation fails.

pub fn inexact(&self) -> bool

Reports whether the inexact flag is set.

Operations set this flag when one or more nonzero coefficient digits were discarded during rounding from a result.

pub fn invalid_context(&self) -> bool

Reports whether the invalid context flag is set.

Operations set this flag if they detect an invalid context.

It should not be possible to pass an invalid context to an operation using this crate, but this method is nonetheless provided for completeness.

pub fn invalid_operation(&self) -> bool

Reports whether the invalid operation flag is set.

Various operations set this flag in response to invalid arguments.

pub fn overflow(&self) -> bool

Reports whether the overflow flag is set.

Operations set this flag when the exponent of a result is too large to be represented.

pub fn clamped(&self) -> bool

Reports whether the clamped flag is set.

Operations set this flag when the exponent of a result has been altered or constrained in order to fit the constraints of a specific concrete representation.

pub fn rounded(&self) -> bool

Reports whether the rounded flag is set.

Operations set this flag when one or more zero or nonzero coefficient digits were discarded from a result.

pub fn subnormal(&self) -> bool

Reports whether the subnormal flag is set.

Operations set this flag when a result's adjusted exponent is less than E_min before any rounding.

pub fn underflow(&self) -> bool

Reports whether the underflow flag is set.

Operations set this flag when a result is both subnormal and inexact.

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Status

impl Debug for Status

fn fmt(&self, f: &mut Formatter<'_>) -> Result
