Struct fidl_fuchsia_io::ReadableProxy

pub struct ReadableProxy { /* private fields */ }

Implementations

impl ReadableProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for Readable

pub fn take_event_stream(&self) -> ReadableEventStream

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

Panics

Panics if the event stream was already taken.

pub fn read(&self, count: u64) -> QueryResponseFut<ReadableReadResult>

Reads up to ‘count’ bytes at the seek offset. The seek offset is moved forward by the number of bytes read.

Invariants

• The returned data.length will never be greater than count.
• If data.length is less than count, it means that the seek offset has reached the end of file as part of this operation.
• If data.length is zero while count is not, it means that the seek offset is already at or beyond the end of file, and no data could be read.
• If count is zero, the server should perform all the checks ensuring read access without actually read anything, and return an empty data vector.

This method requires the [Rights.READ_BYTES] right.

Returns ZX_ERR_OUT_OF_RANGE if count is greater than MAX_TRANSFER_SIZE.
