Enum HostResourceAccessKind 

#[repr(u32)]
pub enum HostResourceAccessKind {
    Deny = 0,
    Allow = 1,
    DenyCors = 2,
}

Kind of cross origin resource access allowed for host resources during download. Note that other normal access checks like same origin DOM access check and Content Security Policy still apply. The following table illustrates the host resource cross origin access according to access context and COREWEBVIEW2_HOST_RESOURCE_ACCESS_KIND.

Cross Origin Access Context	DENY	ALLOW	DENY_CORS
From DOM like src of img, script or iframe element	Deny	Allow	Allow
From Script like Fetch or XMLHttpRequest	Deny	Allow	Deny

Variants

Deny = 0

All cross origin resource access is denied, including normal sub resource access as src of a script or image element.

Allow = 1

All cross origin resource access is allowed, including accesses that are subject to Cross-Origin Resource Sharing(CORS) check. The behavior is similar to a web site sends back http header Access-Control-Allow-Origin: *.

DenyCors = 2

Cross origin resource access is allowed for normal sub resource access like as src of a script or image element, while any access that subjects to CORS check will be denied. See Cross-Origin Resource Sharing for more information.

Trait Implementations

impl Clone for HostResourceAccessKind

fn clone(&self) -> HostResourceAccessKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostResourceAccessKind

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

Formats the value using the given formatter.

impl PartialEq for HostResourceAccessKind

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