Enum cbor::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)

Methods

impl Int

fn from_u64(n: u64) -> Int

fn from_i64(n: i64) -> Int

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.

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

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

Trait Implementations

impl Ord for Int

fn cmp(&self, __arg_0: &Int) -> Ordering

This method returns an Ordering between self and other.

impl PartialOrd for Int

fn partial_cmp(&self, __arg_0: &Int) -> Option<Ordering>

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

fn lt(&self, __arg_0: &Int) -> bool

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

fn le(&self, __arg_0: &Int) -> bool

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

fn gt(&self, __arg_0: &Int) -> bool

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

fn ge(&self, __arg_0: &Int) -> bool

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

impl Eq for Int

impl PartialEq for Int

fn eq(&self, __arg_0: &Int) -> bool

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

fn ne(&self, __arg_0: &Int) -> bool

This method tests for !=.

impl Hash for Int

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

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

Feeds a slice of this type into the state provided.

impl Debug for Int

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Copy for Int

impl Clone for Int

fn clone(&self) -> Int

Returns a copy of the value.

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

Performs copy-assignment from source.
