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>,

    /* 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.

Trait Implementations

impl Debug for NavigationState

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

Formats the value using the given formatter.

impl Decode<NavigationState> 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<'_>, 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> for &mut NavigationState

unsafe fn encode( self, encoder: &mut Encoder<'_>, 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

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 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.
