• ParenHelper 🔒
  Helper type to display either foo or (foo).

Enums

• Associativity 🔒
  Operator associativity.
• Sugg

Constants

• EMPTY
  a constant represents an empty string, for convenience.
• ONE
  Literal constant 1, for convenience.
• ZERO
  Literal constant 0, for convenience.

Traits

• DiagnosticExt
  Convenience extension trait for Diagnostic.

Functions

• associativity 🔒
  Returns the associativity/fixity of an operator. The difference with AssocOp::fixity is that an operator can be both left and right associative (such as +: a + b + c == (a + b) + c == a + (b + c).
• astbinop2assignop 🔒
  Converts an ast::BinOp to the corresponding assigning binary operator.
• binop_to_string 🔒
  Generates a string from the operator and both sides.
• deref_closure_args
  Build suggestion gradually by handling closure arg specific usages, such as explicit deref and borrowing cases. Returns None if no such use cases have been triggered in closure body
• has_enclosing_paren
  Returns 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.
