Enum cborian::value::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

pub fn clone(&self) -> Int

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Int

impl Debug for Int

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

Formats the value using the given formatter.

impl Eq for Int

impl Hash for Int

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Ord for Int

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Int> for Int

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

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

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

This method tests for !=.

impl PartialOrd<Int> for Int

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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