Struct LeaseDependency 

pub struct LeaseDependency {
    pub requires_token: Option<Event>,
    pub requires_level: Option<u8>,
    pub requires_level_by_preference: Option<Vec<u8>>,
    /* private fields */
}

Fields

requires_token: Option<Event>

Must supply a token registered via the RegisterDependencyToken call of the required element’s ElementControl protocol.

requires_level: Option<u8>

Level of the element required. Most clients will want to use this, but for forward compatibility, requires_level_by_preference may be used instead.

requires_level_by_preference: Option<Vec<u8>>

Advanced Options

(Optional) For forward compatibility, the list of levels in decreasing preferential order that power broker should attempt to make required for this dependency to be satisfied. The first level in list that is a valid level will become the required level. If this is set, requires_level will be ignored.

Platform clients can use this list to keep backwards compatibility with dependencies by providing multiple levels that the dependency may have implemented in older API levels.

Trait Implementations

impl Debug for LeaseDependency

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

Formats the value using the given formatter.

impl Decode<LeaseDependency, DefaultFuchsiaResourceDialect> for LeaseDependency

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 LeaseDependency

fn default() -> LeaseDependency

Returns the “default value” for a type.

impl Encode<LeaseDependency, DefaultFuchsiaResourceDialect> for &mut LeaseDependency

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 LeaseDependency

fn eq(&self, other: &LeaseDependency) -> 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 LeaseDependency

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

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 LeaseDependency

type Owned = LeaseDependency

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.
