class RuboCop::Cop::Layout::SpaceAfterColon
Checks for colon (:) not followed by some kind of space. N.B. this cop does not handle spaces after a ternary operator, which are instead handled by Layout/SpaceAroundOperators.
@example
# bad def f(a:, b:2); {a:3}; end # good def f(a:, b: 2); {a: 3}; end
