pub trait Datum: Sized {
// Required methods
fn to_datum(&self) -> Result<Vec<u8>, Box<dyn StdError + Sync + Send>>;
fn from_datum(b: Vec<u8>) -> Result<Self, Box<dyn StdError + Sync + Send>>;
}Expand description
A datum represents a single item in the database. Any type used as
key or value needs to implement Datum.
Any type implementing Serialize and Deserialize also
implements Datum.
Required Methods§
fn to_datum(&self) -> Result<Vec<u8>, Box<dyn StdError + Sync + Send>>
fn from_datum(b: Vec<u8>) -> Result<Self, Box<dyn StdError + Sync + Send>>
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
