Implementations

impl FormatVersion

pub fn is_supported(&self) -> bool

Check if this format version is supported

V2 and V3 are supported. V1 and unknown versions are not.

pub fn needs_migration_to_current(&self) -> bool

Check if this format needs migration to current version

V2 needs migration to V3. V3 is current.

pub fn as_u32(&self) -> u32

Get the numeric version value

Trait Implementations

impl Clone for FormatVersion

fn clone(&self) -> FormatVersion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FormatVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FormatVersion

fn eq(&self, other: &FormatVersion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
