Struct UpdateInfo

pub struct UpdateInfo {
    pub download_size: Option<u64>,
    /* private fields */
}

Metadata for an update. Once a field is populated during an installation attempt, the value will not change.

Fields

download_size: Option<u64>

The total number of bytes that may be downloaded to apply this update. Optional, the installer may not be able to provide this value.

Trait Implementations

impl Clone for UpdateInfo

fn clone(&self) -> UpdateInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UpdateInfo

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

Formats the value using the given formatter.

impl<D> Decode<UpdateInfo, D> for UpdateInfo

where D: ResourceDialect,

fn new_empty() -> UpdateInfo

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<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

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

impl Default for UpdateInfo

fn default() -> UpdateInfo

Returns the “default value” for a type.

impl<D> Encode<UpdateInfo, D> for &UpdateInfo

where D: ResourceDialect,

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

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

impl PartialEq for UpdateInfo

fn eq(&self, other: &UpdateInfo) -> 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 TypeMarker for UpdateInfo

type Owned = UpdateInfo

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.

impl ValueTypeMarker for UpdateInfo

type Borrowed<'a> = &'a UpdateInfo

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

fn borrow( value: &<UpdateInfo as TypeMarker>::Owned, ) -> <UpdateInfo as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
