Struct OffsetMapProxy

pub struct OffsetMapProxy { /* private fields */ }

Implementations

impl OffsetMapProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.block/OffsetMap.

pub fn take_event_stream(&self) -> OffsetMapEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn query( &self, source_block_offset: u64, length: u64, ) -> QueryResponseFut<OffsetMapQueryResult, DefaultFuchsiaResourceDialect>

Looks up mappings which contain [source_block_offset, source_block_offset + length). The returned mappings will always overlap with a prefix of the requested range, but might not contain the entire range (for example if there are many discontiguous extents). The caller can simply repeat the call to query for the remaining suffix of the range.

These mappings are guaranteed to be stable in the lifetime of the OffsetMap connection.
