Add iceberg and iceberg-catalog-rest into Cargo.toml dependencies:
iceberg = "0.6.0" iceberg-catalog-rest = "0.6.0"
using cargo add:
$ cargo add iceberg iceberg-catalog-rest
iceberg is under active development, you may want to use the git version instead:
iceberg = { git = "https://github.com/apache/iceberg-rust", rev = "commit-hash" }
