Enum CrossOriginOpenerPolicyValue 

pub enum CrossOriginOpenerPolicyValue {
    UnsafeNone,
    SameOriginAllowPopups,
    SameOrigin,
    NoopenerAllowPopups,
    Unknown(Box<str>),
}

Opener-policy token values per the HTML Standard.

Per HTML § the-coop-headers, these are the four token values a Cross-Origin-Opener-Policy header may carry. The spec explicitly excludes same-origin-plus-COEP from the valid wire values — that token is the computed opener policy assigned when a same-origin COOP is combined with a cross-origin-isolating COEP, and the COOP header parser rejects it. It’s intentionally not modelled here.

The auto-generated Unknown variant is reachable only via direct construction; the COOP decoder uses strict parsing and rejects any token outside the spec set.

Variants

UnsafeNone

unsafe-none — the spec default when the header is absent.

SameOriginAllowPopups

same-origin-allow-popups — same-origin opener relationships are preserved, popups remain attached.

SameOrigin

same-origin — strict isolation; cross-origin openers are severed from this window.

NoopenerAllowPopups

noopener-allow-popups — added 2024, severs the opener while still letting popups open.

Unknown(Box<str>)

Implementations

Trait Implementations

impl Clone for CrossOriginOpenerPolicyValue

fn clone(&self) -> CrossOriginOpenerPolicyValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrossOriginOpenerPolicyValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CrossOriginOpenerPolicyValue

fn deserialize<D>( deserializer: D, ) -> Result<CrossOriginOpenerPolicyValue, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CrossOriginOpenerPolicyValue

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

Formats the value using the given formatter.

impl Eq for CrossOriginOpenerPolicyValue

impl<'a> From<&'a str> for CrossOriginOpenerPolicyValue

fn from(s: &'a str) -> CrossOriginOpenerPolicyValue

Converts to this type from the input type.

impl From<String> for CrossOriginOpenerPolicyValue

fn from(s: String) -> CrossOriginOpenerPolicyValue

Converts to this type from the input type.

impl FromStr for CrossOriginOpenerPolicyValue

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str( s: &str, ) -> Result<CrossOriginOpenerPolicyValue, <CrossOriginOpenerPolicyValue as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for CrossOriginOpenerPolicyValue

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CrossOriginOpenerPolicyValue

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

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
