Struct Identifier 

pub struct Identifier { /* private fields */ }

Identifies a catalog object (e.g. a table) by database and object name.

Corresponds to org.apache.paimon.catalog.Identifier. The object name may be a table name or a qualified name like table$branch_foo or table$snapshots for system tables.

Implementations

impl Identifier

pub fn new(database: impl Into<String>, object: impl Into<String>) -> Self

Create an identifier from database and object name.

pub fn database(&self) -> &str

Database name.

pub fn object(&self) -> &str

Full object name (table name, or with branch/system suffix).

pub fn full_name(&self) -> String

Full name: when database is UNKNOWN_DATABASE, returns only the object; otherwise returns database.object.

pub fn parsed_object_name(&self) -> Result<ParsedObjectName>

Parse the object name into table, branch, and system-table components.

pub fn table_name(&self) -> Result<String>

pub fn branch_name(&self) -> Result<Option<String>>

pub fn branch_name_or_default(&self) -> Result<String>

pub fn system_table_name(&self) -> Result<Option<String>>
