Struct fixed_decimal::FixedInteger

pub struct FixedInteger(FixedDecimal);

A FixedInteger is a FixedDecimal with no fractional part.

Examples

use fixed_decimal::Error;
use fixed_decimal::FixedDecimal;
use fixed_decimal::FixedInteger;

assert_eq!(
    FixedDecimal::from(FixedInteger::from(5)),
    FixedDecimal::from(5)
);
assert_eq!(
    FixedInteger::try_from(FixedDecimal::from(5)),
    Ok(FixedInteger::from(5))
);
assert_eq!(
    FixedInteger::try_from(FixedDecimal::from_str("05").unwrap()),
    Ok(FixedInteger::from_str("05").unwrap())
);
assert_eq!(
    FixedInteger::try_from(FixedDecimal::from_str("5.0").unwrap()),
    Err(Error::Limit)
);

Trait Implementations

impl Clone for FixedInteger

fn clone(&self) -> FixedInteger

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FixedInteger

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

Formats the value using the given formatter.

impl Default for FixedInteger

fn default() -> FixedInteger

Returns the “default value” for a type.

impl From<FixedInteger> for FixedDecimal

fn from(value: FixedInteger) -> Self

Converts to this type from the input type.

impl From<i128> for FixedInteger

fn from(value: i128) -> Self

Converts to this type from the input type.

impl From<i16> for FixedInteger

fn from(value: i16) -> Self

Converts to this type from the input type.

impl From<i32> for FixedInteger

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<i64> for FixedInteger

fn from(value: i64) -> Self

Converts to this type from the input type.

impl From<i8> for FixedInteger

fn from(value: i8) -> Self

Converts to this type from the input type.

impl From<isize> for FixedInteger

fn from(value: isize) -> Self

Converts to this type from the input type.

impl From<u128> for FixedInteger

fn from(value: u128) -> Self

Converts to this type from the input type.

impl From<u16> for FixedInteger

fn from(value: u16) -> Self

Converts to this type from the input type.

impl From<u32> for FixedInteger

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<u64> for FixedInteger

fn from(value: u64) -> Self

Converts to this type from the input type.

impl From<u8> for FixedInteger

fn from(value: u8) -> Self

Converts to this type from the input type.

impl From<usize> for FixedInteger

fn from(value: usize) -> Self

Converts to this type from the input type.

impl FromStr for FixedInteger

type Err = FixedDecimalError

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for FixedInteger

fn eq(&self, other: &FixedInteger) -> 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.

impl TryFrom<&[u8]> for FixedInteger

type Error = FixedDecimalError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Error>

Performs the conversion.

impl TryFrom<FixedDecimal> for FixedInteger

type Error = FixedDecimalError

The type returned in the event of a conversion error.

fn try_from(value: FixedDecimal) -> Result<Self, Error>

Performs the conversion.

impl Writeable for FixedInteger

fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result

Writes a string to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to_parts, and discards any Part annotations.

fn write_to_parts<S>(&self, sink: &mut S) -> Result<(), Error>

where S: PartsWrite + ?Sized,

Write bytes and Part annotations to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to, and doesn’t produce any Part annotations.

fn writeable_length_hint(&self) -> LengthHint

Returns a hint for the number of UTF-8 bytes that will be written to the sink.

fn write_to_string(&self) -> Cow<'_, str>

Creates a new String with the data from this Writeable. Like ToString, but smaller and faster.

fn writeable_cmp_bytes(&self, other: &[u8]) -> Ordering

Compares the contents of this Writeable to the given bytes without allocating a String to hold the Writeable contents.
