Enum Int 

pub enum Int {
    Neg(u64),
    Pos(u64),
}

Type to represent all possible CBOR integer values.

Since the encoding of negative integers (major type 1) follows unsigned integers (major type 0), mapping negative integers to i8, i16, i32 or i64 can result in integer overflows. If all possible values should be handled, this type can be used.

Variants

Neg(u64)

Pos(u64)

Implementations

impl Int

pub fn from_u64(n: u64) -> Int

pub fn from_i64(n: i64) -> Int

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

Map this value to an i64. If the value does not fit within [i64::MIN, i64::MAX], None is returned instead.

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

Map this value to a u64. If the value is negative, None is returned instead.

Trait Implementations

impl Clone for Int

fn clone(&self) -> Int

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Int

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

Formats the value using the given formatter.

impl Hash for Int

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Int

fn cmp(&self, other: &Int) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Int

fn eq(&self, other: &Int) -> 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 PartialOrd for Int

fn partial_cmp(&self, other: &Int) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
