Session configuration.

Fields

descriptors: Option<Vmo>

VMO containing the descriptors. Required.

16-bit indices transmitted over the FIFOs index a descriptor in this VMO (byte offset = descriptor_length * 8 * index).

data: Option<Vmo>

VMO containing frame data. Required.

Descriptors contain byte-offsets that are used to index arbitrary regions in data.

descriptor_version: Option<u8>

Requested descriptor version. Required.

If the network device does not support the requested descriptor version, [Device.OpenSession] fails with ZX_ERR_NOT_SUPPORTED.

descriptor_length: Option<u8>

Descriptor length, in 64-bit words. Required.

The length of each descriptor in the descriptors VMO. This is used as a multiplier to find byte offsets in descriptors given a descriptor index passed through the rx or tx FIFOs.

descriptor_count: Option<u16>

Total number of descriptors that can be used by this session. Required.

Descriptor indices transferred through either the rx or tx FIFO must be in the range [0, descriptor_count).

options: Option<SessionFlags>

Extra options. Interpreted as empty bitmask if absent.

Implementations

impl SessionInfo

pub const EMPTY: Self = _

An empty table with every field set to None.

Trait Implementations

impl Debug for SessionInfo

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

Formats the value using the given formatter.

impl Decodable for SessionInfo

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for SessionInfo

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<()>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Layout for SessionInfo

fn inline_align(_context: &Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: &Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl PartialEq<SessionInfo> for SessionInfo

fn eq(&self, other: &SessionInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
