pub struct Utf8String { /* private fields */ }
Expand description

Represents an UTF-8 MessagePack string type.

According to the MessagePack spec, string objects may contain invalid byte sequence and the behavior of a deserializer depends on the actual implementation when it received invalid byte sequence. Deserializers should provide functionality to get the original byte array so that applications can decide how to handle the object.

Summarizing, it’s prohibited to instantiate a string type with invalid UTF-8 sequences, however it is possible to obtain an underlying bytes that were attempted to convert to a String. This may happen when trying to unpack strings that were decoded using older MessagePack spec with raw types instead of string/binary.

Implementations

Returns true if the string is valid UTF-8.

Returns true if the string contains invalid UTF-8 sequence.

Returns the string reference if the string is valid UTF-8, or else None.

Returns the underlying Utf8Error if the string contains invalud UTF-8 sequence, or else None.

Returns a byte slice of this Utf8String’s contents.

Consumes this object, yielding the string if the string is valid UTF-8, or else None.

Converts a Utf8String into a byte vector.
