Struct RESTCatalog 

pub struct RESTCatalog { /* private fields */ }

REST catalog implementation.

This catalog communicates with a Paimon REST catalog server for all metadata operations (database and table CRUD).

Corresponds to Python RESTCatalog in pypaimon/catalog/rest/rest_catalog.py.

Implementations

impl RESTCatalog

pub async fn new(options: Options, config_required: bool) -> Result<Self>

Create a new REST catalog.

Arguments

• options - Configuration options containing URI, warehouse, etc.
• config_required - Whether to fetch config from server and merge with options.

Errors

Returns an error if required options are missing or if initialization fails.

pub fn warehouse(&self) -> &str

Get the warehouse path.

pub fn options(&self) -> &Options

Get the catalog options.

pub fn data_token_enabled(&self) -> bool

Whether data token is enabled.

pub async fn list_databases_paged( &self, max_results: Option<u32>, page_token: Option<&str>, database_name_pattern: Option<&str>, ) -> Result<PagedList<String>>

List databases with pagination.
