Struct pot::format::Integer

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

An integer type that can safely convert between other number types using compile-time evaluation.

Implementations

impl Integer

pub const fn is_zero(&self) -> bool

Returns true if the value contained is zero.

pub const fn as_i8(&self) -> Result<i8, Error>

Returns the contained value as an i8, or an error if the value is unable to fit.

pub const fn as_u8(&self) -> Result<u8, Error>

Returns the contained value as an u8, or an error if the value is unable to fit.

pub const fn as_i16(&self) -> Result<i16, Error>

Returns the contained value as an i16, or an error if the value is unable to fit.

pub const fn as_u16(&self) -> Result<u16, Error>

Returns the contained value as an u16, or an error if the value is unable to fit.

pub const fn as_i32(&self) -> Result<i32, Error>

Returns the contained value as an i32, or an error if the value is unable to fit.

pub const fn as_u32(&self) -> Result<u32, Error>

Returns the contained value as an u32, or an error if the value is unable to fit.

pub const fn as_i64(&self) -> Result<i64, Error>

Returns the contained value as an i64, or an error if the value is unable to fit.

pub const fn as_i128(&self) -> Result<i128, Error>

Returns the contained value as an i64, or an error if the value is unable to fit.

pub const fn as_u64(&self) -> Result<u64, Error>

Returns the contained value as an u64, or an error if the value is unable to fit.

pub const fn as_u128(&self) -> Result<u128, Error>

Returns the contained value as an u64, or an error if the value is unable to fit.

pub fn write_to<W: WriteBytesExt>(&self, writer: W) -> Result<usize>

Writes this value using the smallest form possible.

pub fn read_from<R: ReadBytesExt>( kind: Kind, byte_len: usize, reader: &mut R, ) -> Result<Self, Error>

Reads an integer based on the atom header (kind and byte_len). byte_len should be the argument from the atom header directly.

pub fn as_f32(&self) -> Result<f32, Error>

Converts this integer to an f32, but only if it can be done without losing precision.

pub fn as_f64(&self) -> Result<f64, Error>

Converts this integer to an f64, but only if it can be done without losing precision.

pub fn as_float(&self) -> Result<Float, Error>

Converts this integer to an f64, but only if it can be done without losing precision.

Trait Implementations

impl Clone for Integer

fn clone(&self) -> Integer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Integer

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

Formats the value using the given formatter.

impl Display for Integer

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

Formats the value using the given formatter.

impl From<i128> for Integer

fn from(value: i128) -> Self

Converts to this type from the input type.

impl From<i16> for Integer

fn from(value: i16) -> Self

Converts to this type from the input type.

impl From<i32> for Integer

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Integer

fn from(value: i64) -> Self

Converts to this type from the input type.

impl From<i8> for Integer

fn from(value: i8) -> Self

Converts to this type from the input type.

impl From<u128> for Integer

fn from(value: u128) -> Self

Converts to this type from the input type.

impl From<u16> for Integer

fn from(value: u16) -> Self

impl PartialEq for Integer

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

This method tests for self and other values to be equal, and is used by ==.

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

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