Trait minicbor::encode::Encode [−][src]

}Expand description
A type that can be encoded to CBOR.
If this type’s CBOR encoding is meant to be decoded by Decode impls
derived with minicbor_derive it is advisable to only produce a
single CBOR data item. Tagging, maps or arrays can and should be used
for multiple values.
Required methods
Provided methods
Is this value of Self a nil value?
This method is primarily used by minicbor-derive.
Some types have a special value to denote the concept of “nothing”, aka
nil. An example is the Option type with its None value. This
method–if overriden–allows checking if a value is such a special nil
value.
NB: A type implementing Encode with an overriden Encode::is_nil
method should also override Decode::nil if it implements Decode
at all.
