Struct NavigationState

pub struct NavigationState {
    pub url: Option<String>,
    pub title: Option<String>,
    pub page_type: Option<PageType>,
    pub can_go_forward: Option<bool>,
    pub can_go_back: Option<bool>,
    pub is_main_document_loaded: Option<bool>,
    pub favicon: Option<Favicon>,
    pub error_detail: Option<ErrorDetail>,
    /* private fields */
}

Contains information about the [Frame]’s navigation state.

Fields

url: Option<String>

The page’s URL.

title: Option<String>

The user-visible page title. While W3C style recommendation is that HTML TITLE tags not exceed 64 characters in length, there is no actual limit.

page_type: Option<PageType>

Indicates whether this was a navigation to an error page.

can_go_forward: Option<bool>

Indicates if there is a following navigation.

can_go_back: Option<bool>

Indicates if there is a previous navigation.

is_main_document_loaded: Option<bool>

Indicates that the main document’s statically declared resources have been loaded.

favicon: Option<Favicon>

Current favicon for the page. The field is set only when the FAVICON flag is set for the NavigationEventListener and the favicon has changed.

error_detail: Option<ErrorDetail>

Indicates type of the error when page_type is set to ERROR.

Trait Implementations

impl Debug for NavigationState

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

Formats the value using the given formatter.

impl Decode<NavigationState, DefaultFuchsiaResourceDialect> for NavigationState

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 NavigationState

fn default() -> NavigationState

Returns the “default value” for a type.

impl Encode<NavigationState, DefaultFuchsiaResourceDialect> for &mut NavigationState

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 NavigationState

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

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

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 NavigationState

type Owned = NavigationState

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.
