Enum TabularMetadataRef

pub enum TabularMetadataRef<'a> {
    Table(&'a TableMetadata),
    View(&'a ViewMetadata),
    MaterializedView(&'a MaterializedViewMetadata),
}

A reference wrapper for different types of tabular metadata

This enum provides a way to reference the different types of tabular metadata (tables, views, materialized views) without taking ownership. It implements common functionality for accessing metadata properties across all tabular types.

Variants

Table(&'a TableMetadata)

Table metadata

View(&'a ViewMetadata)

View metadata

MaterializedView(&'a MaterializedViewMetadata)

Materialized view metadata

Implementations

impl TabularMetadataRef<'_>

pub fn uuid(&self) -> &Uuid

Returns the UUID of the tabular object

Returns

• A reference to the UUID that uniquely identifies this table, view, or materialized view

pub fn location(&self) -> &str

Returns the storage location of the tabular object

Returns

• A string reference to the base storage location (e.g. S3 path, file path) where this table, view, or materialized view’s data is stored

pub fn sequence_number(&self) -> i64

Returns the current sequence number or version ID of the tabular object

Returns

• For tables: The last sequence number used to create a snapshot
• For views and materialized views: The current version ID

pub fn current_schema(&self, branch: Option<&str>) -> Result<&Schema, Error>

Returns the current schema for the tabular object

Arguments

• branch - Optional branch name to get schema from

Returns

• Ok(&Schema) - The current schema for this table, view, or materialized view
• Err(Error) - If the schema cannot be retrieved
