The Settings struct previously contained the fields:
pub enabled: HashableHashSet<RuleCode>,
pub fixable: HashableHashSet<RuleCode>,
This commit merges both fields into one by introducing a new
RuleTable type, wrapping HashableHashMap<RuleCode, bool>,
which has the following benefits:
1. It makes the invalid state that a rule is
disabled but fixable unrepresentable.
2. It encapsulates the implementation details of the table.
(It currently uses an FxHashMap but that may change.)
3. It results in more readable code.
settings.rules.enabled(rule)
settings.rules.should_fix(rule)
is more readable than:
settings.enabled.contains(rule)
settings.fixable.contains(rule)
The primary motivation is that we can now robustly detect `\` continuations due to the addition of `Tok::NonLogicalNewline`. This PR generalizes the approach we took to comments (track all lines that contain any comments), and applies it to continuations too.
