Implementations

impl Value

pub fn type_tag(&self) -> u8

Returns a tag byte identifying this value’s type

pub fn deserialize_from_type_tag( type_tag: u8, reader: &mut dyn Read, ) -> Result<Self>

Deserialize a value from a reader based on its type tag

Arguments

• type_tag - The type tag of the value
• reader - The reader to read the value data from

Returns

The deserialized value or an IO error
