Struct GptManager 

pub struct GptManager { /* private fields */ }

Runs a GPT device.

Implementations

impl GptManager

pub async fn new( block_proxy: BlockProxy, partitions_dir: Arc<Simple>, ) -> Result<Arc<Self>, Error>

pub async fn new_with_mapper( block_proxy: BlockProxy, mapper_proxy: Option<MapperProxy>, partitions_dir: Arc<Simple>, ) -> Result<Arc<Self>, Error>

Creates a new GptManager with an optional mapper proxy and default configuration.

pub async fn new_with_config( block_proxy: BlockProxy, partitions_dir: Arc<Simple>, config: Config, ) -> Result<Arc<Self>, Error>

pub async fn new_with_config_and_mapper( block_proxy: BlockProxy, mapper_proxy: Option<MapperProxy>, partitions_dir: Arc<Simple>, config: Config, ) -> Result<Arc<Self>, Error>

Creates a new GptManager with custom config and an optional mapper proxy.

pub async fn mapper_session_proxy(&self) -> &MapperSessionProxy

Returns a reference to the parent device’s fblock::MapperSessionProxy.

Panics

Panics if the parent device was not configured with a mapper proxy.

pub fn next_partition_key(&self) -> u64

Allocates and returns the next unique partition key for mapper sessions.

pub async fn register_mappings( &self, key: u64, offset_map: &OffsetMap, ) -> Result<(), Error>

Registers the extent mapping for a partition under key with the parent mapper session.

Panics

Panics if the parent device was not configured with a mapper proxy.

pub fn has_mapper(&self) -> bool

Returns true if this GPT instance was configured with a mapper proxy.

pub fn block_size(&self) -> u32

pub fn block_count(&self) -> u64

pub async fn create_transaction(self: &Arc<Self>) -> Result<EventPair, Status>

pub async fn commit_transaction( self: &Arc<Self>, transaction: EventPair, ) -> Result<(), Status>

pub async fn add_partition( &self, request: PartitionsManagerAddPartitionRequest, ) -> Result<(), Status>

pub async fn handle_partitions_requests( &self, gpt_index: usize, requests: PartitionRequestStream, ) -> Result<(), Status>

pub async fn handle_composite_partitions_requests( &self, gpt_indexes: Vec<usize>, requests: OverlayPartitionRequestStream, ) -> Result<(), Status>

pub async fn reset_partition_table( self: &Arc<Self>, partitions: Vec<PartitionInfo>, ) -> Result<(), Status>

pub async fn shutdown(self: Arc<Self>)

Trait Implementations

impl Debug for GptManager

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Drop for GptManager

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
