Struct ReftableStack 

pub struct ReftableStack { /* private fields */ }

Manages the $GIT_DIR/reftable/ directory and tables.list stack.

The stack provides a merged view of all tables, with later tables taking precedence over earlier ones.

Implementations

impl ReftableStack

pub fn open(git_dir: &Path) -> Result<Self>

Open an existing reftable stack.

pub fn read_refs(&self) -> Result<Vec<RefRecord>>

Read a merged view of all ref records.

Later tables override earlier ones. Deletion records cause the ref to be omitted from the result.

pub fn lookup_ref(&self, name: &str) -> Result<Option<RefRecord>>

Look up a single ref across all tables (most recent wins).

pub fn read_logs_for_ref(&self, refname: &str) -> Result<Vec<LogRecord>>

Read merged log records for a specific ref.

pub fn read_all_logs(&self) -> Result<Vec<LogRecord>>

Read all log records across all tables.

pub fn max_update_index(&self) -> Result<u64>

Get the current max update index across all tables.

pub fn add_table(&mut self, data: &[u8], update_index: u64) -> Result<String>

Add a new reftable to the stack.

Writes the table bytes to a new file, then atomically updates tables.list.

pub fn write_ref( &mut self, refname: &str, value: RefValue, log: Option<LogRecord>, opts: &WriteOptions, ) -> Result<()>

Write a ref update (add/update/delete) as a new reftable.

This is the main entry point for updating refs in a reftable repo.

pub fn compact(&mut self) -> Result<()>

Compact all tables into a single table.

pub fn table_names(&self) -> &[String]

Return the list of table filenames in this stack.
