### Is your feature request related to a problem or challenge? I'm trying to implement a custom variant of `ListingTable`, and I'm running into an issue that the following three helper functions are currently not public: https://github.com/apache/datafusion/blob/cf0cba72204e54c8eb05156d372dc5bab248e4ea/datafusion/core/src/datasource/listing/helpers.rs#L313 https://github.com/apache/datafusion/blob/cf0cba72204e54c8eb05156d372dc5bab248e4ea/datafusion/core/src/datasource/listing/helpers.rs#L125 https://github.com/apache/datafusion/blob/cf0cba72204e54c8eb05156d372dc5bab248e4ea/datafusion/core/src/datasource/listing/helpers.rs#L51 That alone prevents me from implementing my own `ListingTable` with an otherwise reasonably level of complexity. ### Describe the solution you'd like I'd like either: * to make those three functions public * or, to provide a way to customise `ListingTable` so I can: * apply extra pruning based on column equivalence, see #10399 * and, use file lists and file statistics that are stored somewhere other than the object store ### Describe alternatives you've considered I'd rather not copy and paste the whole of `/datafusion/core/src/datasource/listing/helpers.rs`, but that seems to be the only way around this. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
