Trait FormatVersion 

pub trait FormatVersion {
    const VERSION: u32;

    // Required method
    fn format_version(&self) -> u32;
}

A value that carries the version of the format it was written in.

A field added within a version takes #[serde(default)], so a value written before the field existed still loads in a self-describing format such as JSON. A change an older value cannot be read under bumps VERSION. An implementer whose value holds another versioned value must bump its own version whenever the inner one’s rises, so that its version alone says whether it reads: nothing checks this for it.

Required Associated Constants

const VERSION: u32

The format version this release writes, and the only one it reads.

Required Methods

fn format_version(&self) -> u32

The format version this value was written in.

Dyn Compatibility

This trait is not dyn compatible.

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