Struct postcard::Deserializer

pub struct Deserializer<'de, F: Flavor<'de>> { /* private fields */ }

A serde compatible deserializer, generic over “Flavors” of deserializing plugins.

Please note that postcard messages are not self-describing and therefore incompatible with internally tagged enums.

Implementations

pub fn from_flavor(flavor: F) -> Self

Obtain a Deserializer from a slice of bytes

pub fn finalize(self) -> Result<F::Remainder>
