Struct BlockModifiers 

#[non_exhaustive]
pub struct BlockModifiers {}

Additional optional information about a block.

This data structure may grow to accommodate future Rust language changes, including the following in-progress RFCs:

• RFC 3680 “Simplify lightweight clones” (async use { ... })
• #149488 “Heterogeneous try blocks” (try bikeshed Option<_> { ... })
