Struct Edition 

pub struct Edition {
    pub id: EditionId,
    pub min_library_version: Option<&'static str>,
}

An edition: a named set of serialized components that can acquire a read-compatibility guarantee, registered with EditionSession::declare_edition. The set itself is computed from the registered EditionInclusions by EditionSession::components_in.

Fields

id: EditionId

The edition identifier. For a core edition, its date records when it freezes.

min_library_version: Option<&'static str>

The minimum version of the edition family’s EditionFamily::origin whose reader supports every member of this edition.

A stable edition may freeze in the release that cuts it. Until that release is cut, its version is not known and this remains None. The version is then backfilled to document the already completed freeze and identify the first released reader supporting every member. A draft has no recorded read-forever guarantee; that does not imply that its behavior is expected to change. Validated against the members’ EditionInclusion::required_vortex_release values: no member may require a version newer than the edition declares.

Implementations

impl Edition

pub fn is_draft(&self) -> bool

A draft is an edition whose min_library_version has not been recorded yet.

This describes the absence of a frozen compatibility guarantee, not necessarily the implementation stability of its members.

Trait Implementations

impl Clone for Edition

fn clone(&self) -> Edition

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

Performs copy-assignment from source.

impl Copy for Edition

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

Formats the value using the given formatter.
