If true, then there may exist break 'a values that aim to break out of this block early. As of this writing, this is not currently permitted in Rust itself, but it is generated as part of catch statements.

recovered: bool

If true, don't emit return value type errors as the parser had to recover from a parse error so this block will not have an appropriate type. A parse error will have been emitted so the compilation will never succeed if this is true.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a copy of the value.

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