Enum bytecodec::ByteCount
[−]
[src]
pub enum ByteCount { Finite(u64), Infinite, Unknown, }
Number of bytes of interest.
Variants
Finite(u64)
Infinite
Unknown
Methods
impl ByteCount
[src]
pub fn is_finite(&self) -> bool
[src]
Returns true
if this is ByteCount::Finite(_)
, otherwise false
.
pub fn is_infinite(&self) -> bool
[src]
Returns true
if this is ByteCount::Infinite
, otherwise false
.
pub fn is_unknow(&self) -> bool
[src]
Returns true
if this is ByteCount::Unknown
, otherwise false
.
pub fn to_u64(&self) -> Option<u64>
[src]
Tries to convert this ByteCount
to an u64
value.
If it is not a ByteCount::Finite(_)
,None
will be returned.
pub fn add_for_decoding(self, other: Self) -> Self
[src]
Adds two ByteCount
instances for decoding (i.e., Decode::requiring_bytes
method).
Rule
Finite(a) + Finite(b) = Finite(a + b)
Infinite + _ = Infinite
_ + Infinite = Infinite
Unknown + Unknown = Unknown
Finite(0) + Unknown = Unknown
Unknown + Finite(0) = Unknown
Finite(a) + Unknown = Finite(a)
Unknown + Finite(b) = Finite(b)
pub fn add_for_encoding(self, other: Self) -> Self
[src]
Adds two ByteCount
instances for encoding (i.e., Encode::requiring_bytes
method).
Rule
Finite(a) + Finite(b) = Finite(a + b)
Infinite + _ = Infinite
_ + Infinite = Infinite
Unknown + _ = Unknown
_ + Unknown = Unknown
