Enum webkit2gtk::PolicyDecisionType

#[non_exhaustive]
pub enum PolicyDecisionType {
    NavigationAction,
    NewWindowAction,
    Response,
    // some variants omitted
}

Enum values used for determining the type of a policy decision during signal::WebView::decide-policy.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NavigationAction

This type of policy decision is requested when WebKit is about to navigate to a new page in either the main frame or a subframe. Acceptable policy decisions are either PolicyDecisionExt::use_() or PolicyDecisionExt::ignore(). This type of policy decision is always a NavigationPolicyDecision.

NewWindowAction

This type of policy decision is requested when WebKit is about to create a new window. Acceptable policy decisions are either PolicyDecisionExt::use_() or PolicyDecisionExt::ignore(). This type of policy decision is always a NavigationPolicyDecision. These decisions are useful for implementing special actions for new windows, such as forcing the new window to open in a tab when a keyboard modifier is active or handling a special target attribute on <a> elements.

Response

This type of decision is used when WebKit has received a response for a network resource and is about to start the load. Note that these resources include all subresources of a page such as images and stylesheets as well as main documents. Appropriate policy responses to this decision are PolicyDecisionExt::use_(), PolicyDecisionExt::ignore(), or PolicyDecisionExt::download(). This type of policy decision is always a ResponsePolicyDecision. This decision is useful for forcing some types of resources to be downloaded rather than rendered in the WebView or to block the transfer of resources entirely.

Trait Implementations

impl Clone for PolicyDecisionType

fn clone(&self) -> PolicyDecisionType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyDecisionType

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

Formats the value using the given formatter.

impl Display for PolicyDecisionType

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

Formats the value using the given formatter.

impl<'a> FromValue<'a> for PolicyDecisionType

type Checker = GenericValueTypeChecker<PolicyDecisionType>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl Hash for PolicyDecisionType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl Ord for PolicyDecisionType

fn cmp(&self, other: &PolicyDecisionType) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<PolicyDecisionType> for PolicyDecisionType

fn eq(&self, other: &PolicyDecisionType) -> bool

This method tests for self and other values to be equal, and is used by ==.

const 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 PartialOrd<PolicyDecisionType> for PolicyDecisionType

fn partial_cmp(&self, other: &PolicyDecisionType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

const fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

const fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for PolicyDecisionType

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ValueType for PolicyDecisionType

type Type = PolicyDecisionType

Type to get the Type from.

impl Copy for PolicyDecisionType
