Trait Implementations

impl<'a, 'tcx> Clone for VariantInfo<'a, 'tcx>

fn clone(&self) -> VariantInfo<'a, 'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
