Struct postcard::Deserializer [−][src]
pub struct Deserializer<'de> { /* fields omitted */ }
Expand description
A structure for deserializing a postcard message. For now, Deserializer does not implement the same Flavor interface as the serializer does, as messages are typically easier to deserialize in place. This may change in the future for consistency, or to support items that cannot be deserialized in-place, such as compressed message types
