Struct IntegerValue 

pub struct IntegerValue(/* private fields */);

Lossless integer value captured by generated integer range and conversion errors.

The representation is private so future integer-like values can be added without exposing the enum shape. Use the as_* methods to recover a primitive integer only when the conversion is lossless.

Implementations

impl IntegerValue

pub const fn from_i128(value: i128) -> Self

Captures a signed integer value.

pub const fn from_u128(value: u128) -> Self

Captures an unsigned integer value.

pub fn as_i64(self) -> Option<i64>

Returns the value as i64 when it fits exactly.

pub fn as_u64(self) -> Option<u64>

Returns the value as u64 when it fits exactly.

pub fn as_i128(self) -> Option<i128>

Returns the value as i128 when it fits exactly.

pub fn as_u128(self) -> Option<u128>

Returns the value as u128 when it fits exactly.

Trait Implementations

impl Clone for IntegerValue

fn clone(&self) -> IntegerValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntegerValue

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

Formats the value using the given formatter.

impl Display for IntegerValue

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

Formats the value using the given formatter.

impl From<i128> for IntegerValue

fn from(value: i128) -> Self

Converts to this type from the input type.

impl From<i16> for IntegerValue

fn from(value: i16) -> Self

Converts to this type from the input type.

impl From<i32> for IntegerValue

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<i64> for IntegerValue

fn from(value: i64) -> Self

Converts to this type from the input type.

impl From<i8> for IntegerValue

fn from(value: i8) -> Self

Converts to this type from the input type.

impl From<u128> for IntegerValue

fn from(value: u128) -> Self

Converts to this type from the input type.

impl From<u16> for IntegerValue

fn from(value: u16) -> Self

impl PartialEq for IntegerValue

fn eq(&self, other: &IntegerValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Calls the relevant method on Visit to extract data from self.

fn visit_slice(slice: &[Self], visit: &mut dyn Visit)

where Self: Sized,

Calls Visit::visit_primitive_slice() with self.
