const DELIM_STR: &'static str

const LINT_EXPR_IN_PATTERN_MATCHING_CTX: bool

Due to ref pattern, there can be a difference between using { expr } and expr in pattern-matching contexts. This means that we should only lint unused_parens and not unused_braces in this case.

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.
