Struct fidl_fuchsia_web::Favicon

pub struct Favicon {
    pub data: Option<Buffer>,
    pub width: Option<u32>,
    pub height: Option<u32>,
    /* private fields */
}

Used to represent a favicon for a page. An empty table (all fields are unset) is used to indicate that the page doesn’t have a favicon.

Fields

data: Option<Buffer>

The image content encoded as an RGBA bitmap with premultiplied alpha channel. The data is densely packed, so the stride is always 4 * width and the total size is 4 * width * height.

width: Option<u32>

The width of the image.

height: Option<u32>

The height of the image.

Trait Implementations

impl Debug for Favicon

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

Formats the value using the given formatter.

impl Decode<Favicon, DefaultFuchsiaResourceDialect> for Favicon

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 Favicon

fn default() -> Favicon

Returns the “default value” for a type.

impl Encode<Favicon, DefaultFuchsiaResourceDialect> for &mut Favicon

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 Favicon

fn eq(&self, other: &Favicon) -> 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.

impl ResourceTypeMarker for Favicon

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

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 Favicon

type Owned = Favicon

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.
