class RuboCop::Cop::Layout::MultilineHashKeyLineBreaks
Ensures that each key in a multi-line hash starts on a separate line.
@example
# bad { a: 1, b: 2, c: 3 } # good { a: 1, b: 2, c: 3 } # good { a: 1, b: { c: 3, } }
@example AllowMultilineFinalElement: false (default)
# bad { a: 1, b: { c: 3, }}
@example AllowMultilineFinalElement: true
# good { a: 1, b: { c: 3, }}
