Antoine Pitrou commented on ARROW-2399: --------------------------------------- Chiming in again: while arrays are immutable, buffers need not be immutable. In C++, we have both mutable and immutable buffers (and both kinds are allowed to back arrays). > [Rust] Builder<T> should not provide a set() method > --------------------------------------------------- > > Key: ARROW-2399 > URL: https://issues.apache.org/jira/browse/ARROW-2399 > Project: Apache Arrow > Issue Type: Bug > Components: Rust > Reporter: Andy Grove > Priority: Major > Fix For: 0.10.0 > > > Arrays should be immutable, but we have a `set` method on Buffer<T> that > should not be there. > This is only used from the Bitmap struct. Perhaps Bitmap should maintain its > own memory instead and not use Buffer? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
