Enum rustc_parse::parser::pat::EatOrResult

source · [−]

enum EatOrResult {
    TrailingVert,
    AteOr,
    None,
}

Expand description

The result of eat_or_separator. We want to distinguish which case we are in to avoid emitting duplicate diagnostics.

Variants

`TrailingVert`

We recovered from a trailing vert.

`AteOr`

We ate an | (or || and recovered).

`None`

We did not eat anything (i.e. the current token is not | or ||).
