Trait Save 

pub trait Save {
    const VERSION: Version;

    // Required method
    fn save(&self, context: Context<'_>) -> Result<Record<'_>>;
}

Implemented by user types that map to a versioned Record.

This is the primary trait for structured user types. A Save impl describes the versioned schema of Self: its associated VERSION is attached to the Record produced by Self::save.

Enums

Enum types are encoded by returning a Record with a single user key whose name is the variant tag and whose value is the variant’s payload (frequently Value::Null for unit variants). See the crate-level docs for a worked example.

Required Associated Constants

const VERSION: Version

The schema version attached to records produced by this impl.

Loaders compare this against the version stored in the manifest to decide between Load::load and Load::load_legacy.

Required Methods

fn save(&self, context: Context<'_>) -> Result<Record<'_>>

Serialize self into a Record.

Use the supplied Context to request side-car artifact writers. Use the save_fields! macro to populate the record.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
