Add as_ref() to Value and Utf8String (#139).
as_ref() to Value and Utf8String (#139).Implement Deserialize for ValueRef<'de>.
Deserialize for ValueRef<'de>.Deserializer for ValueRef<'de>.Deserializer for &'de ValueRef<'de>.ValueRef.### Fixed - Fix compilation on rustc 1.13.
Enum deserializer can now deserialize newtype variants with more than one element nested.
Fixed double-quoting for strings when formatting a ValueRef using Display trait.
ValueRef using Display trait.### Added - Implement From for std::Error.
From<rmpv::decode::Error> for std::io::Error.Implement Deserializer and Serializer for Value.
Deserializer and Serializer for Value.kind() method for rmpv::decode::Error.Error and Display traits for rmpv::decode::Error.From trait for Value and ValueRef from all integral types, strings, slices and other more.Error::TypeMismatch.Value and ValueRef has been changed and hidden from the user to be able to fully match the spec and to fix round-trip cases.Value and ValueRef to match the spec. An untouched bytes can also be returned on demand as like as Utf8Error with description where invalid byte-sequence happened.Value and ValueRef has been merged into the single one, which is located at rmpv::decode::Error.TypeMismatch variant from value::decode::Error, because there is no way to obtain it.FromUtf8Error variant from value::decode::Error, because there invalid UTF-8 sequences are now supported.ValueRef can be indexed using special index(..) method. Implementing Index trait is not possible due to conflicting signature - ValueRef requires expl
Serde 0.9 support.ValueRef can now be displayed.ValueRef can be indexed using special index(..) method. Implementing Index trait is not possible due to conflicting signature - ValueRef requires explicit lifetime.ErrorKind for Errors.Value now saves integer and floating point numbers directly without intermediate Integer and Float enums. As a result, they were removed.
