[jira] [Updated] (ARROW-10800) [Rust] [Parquet] Provide access to the elements of parquet::record::{List, Map, MapList}

     [ https://issues.apache.org/jira/browse/ARROW-10800?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Moran updated ARROW-10800:
-------------------------------
    Description: When dealing with List, Map, and MapList, ListAccessor and MapAccessor provide type-safe access to elements of the collections if type and position are known. For cases where that information is unavailable, providing access to the underlying Vec of Fields would be extremely beneficial.  (was: When dealing with parquet::record::List, parquet::record::ListAccessor provides type-safe access to elements of the list if type and position are known. For cases where that information is unavailable, providing access to the underlying Vec of Fields would be extremely beneficial.)
