astbinop2assignop

has_enclosing_paren

Return true if sugg is enclosed in parenthesis.

hirbinop2assignop

Converts a hir::BinOp to the corresponding assigning binary operator.

indentation

Returns the indentation before span if there are nothing but [ \t] before it on its line.

make_assoc

Builds the string for <lhs> <op> <rhs> adding parenthesis when necessary.

make_binop

Convenience wrapper around make_assoc and AssocOp::from_ast_binop.

make_unop

Builds the string for <op><expr> adding parenthesis when necessary.
