Struct salsa::Revision

pub struct Revision { /* fields omitted */ }

A unique identifier for the current version of the database; each time an input is changed, the revision number is incremented. Revision is used internally to track which values may need to be recomputed, but is not something you should have to interact with directly as a user of salsa.

Trait Implementations

impl Clone for Revision

fn clone(&self) -> Revision

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for Revision

fn cmp(&self, other: &Revision) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

fn min(self, other: Self) -> Self
