Enum AllowlistSource 

pub enum AllowlistSource {
    SelfOrigin,
    Wildcard,
    Src,
    Unknown(String),
}

Available on crate feature http only.

Allowlist token shapes per the W3C Permissions Policy spec.

The deny-all directive is represented by an empty PermissionsPolicyDirective::allow_list (no None variant here) so that the typed state and the wire form (feature=()) line up one-to-one.

Specific origins (e.g. "https://example.com") land in the auto-generated Unknown variant — use Self::origin to construct one with the required RFC 8941 sf-string double-quoting baked in.

Variants

SelfOrigin

self — same-origin only (no surrounding quotes on the wire, unlike CSP).

Wildcard

* — any origin.

Src

src — legacy <iframe allow=…> token, lets the iframe inherit from its src attribute. Rare outside iframe context.

Unknown(String)

Implementations

impl AllowlistSource

pub fn as_str(&self) -> &str

pub fn as_smol_str(&self) -> SmolStr

impl AllowlistSource

pub fn strict_parse(s: &str) -> Option<AllowlistSource>

Same as FromStr or From<&str> but returning None for unknown values

impl AllowlistSource

pub fn origin(origin: impl AsRef<str>) -> AllowlistSource

Construct an origin allow-list source from a bare origin string — the surrounding RFC 8941 sf-string double-quotes are added for you. Pass https://example.com, not "https://example.com".

Trait Implementations

impl Clone for AllowlistSource

fn clone(&self) -> AllowlistSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllowlistSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AllowlistSource

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AllowlistSource

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

Formats the value using the given formatter.

impl Eq for AllowlistSource

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

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

Converts to this type from the input type.

impl From<String> for AllowlistSource

fn from(s: String) -> AllowlistSource

Converts to this type from the input type.

impl FromStr for AllowlistSource

type Err = Infallible

The associated error which can be returned from parsing.

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

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

impl Hash for AllowlistSource

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 AllowlistSource

fn eq(&self, other: &AllowlistSource) -> 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 Serialize for AllowlistSource

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.
