Expand description
This code is the (cleaned output) generated by pin-project-lite, as it does not support tuple variants.
This is the altered expansion from the following snippet, expanded by
cargo-expand:
use pin_project_lite::pin_project;
pin_project! {
#[project = EitherProj]
pub enum Either<L, R> {
Left {#[pin] left: L},
Right {#[pin] right: R}
}
}
