impl LintPass for UnusedBraces

fn name(&self) -> &'static str

impl UnusedDelimLint for UnusedBraces

const DELIM_STR: &'static str = "braces"

const LINT_EXPR_IN_PATTERN_MATCHING_CTX: bool = false

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.
