Struct DelegatedRxLease

pub struct DelegatedRxLease {
    pub hold_until_frame: Option<u64>,
    pub handle: Option<DelegatedRxLeaseHandle>,
    /* private fields */
}

An aqcuired lease that is propagated up to applications.

Fields

hold_until_frame: Option<u64>

The frame after which the lease in handle can be released.

Agents observing leases must keep track of received frames with an increasing counter to be able to properly relinquish leases after the frame hold_until_frame is fully processed.

This value can be interpreted as either the 1-based index of a given frame or as the total number of exchanged frames so far, which are mathematically equivalent.

This mechanism allows for wake lease handles from received frames to be passed up and keep the system from suspension until the frame is fully processed.

Required.

handle: Option<DelegatedRxLeaseHandle>

A handle representing the held lease.

Required.

Trait Implementations

impl Debug for DelegatedRxLease

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

Formats the value using the given formatter.

impl Decode<DelegatedRxLease, DefaultFuchsiaResourceDialect> for DelegatedRxLease

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

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

Decodes an object of type T from the decoder’s buffers into self.

impl Default for DelegatedRxLease

fn default() -> DelegatedRxLease

Returns the “default value” for a type.

impl Encode<DelegatedRxLease, DefaultFuchsiaResourceDialect> for &mut DelegatedRxLease

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for DelegatedRxLease

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl ResourceTypeMarker for DelegatedRxLease

type Borrowed<'a> = &'a mut DelegatedRxLease

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &mut Self::Owned. There are three cases:

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for DelegatedRxLease

type Owned = DelegatedRxLease

The owned Rust type which this FIDL type decodes into.

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 alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.
