Functions

• return_true 🔒
  This method exists solely for the purpose of making ColumnType nullable by default in unit tests. The default value of a bool is false, and the only way to make an object take on any other value by default is to pass it a function that returns the desired default value. See https://github.com/serde-rs/serde/issues/1030

  The name of a column in a RelationDesc.
