Enum cbor::value::Int
[−]
[src]
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
[src]
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.
