Struct PermissionsPolicyDirective 

pub struct PermissionsPolicyDirective {
    pub name: PermissionsPolicyDirectiveName,
    pub allow_list: SmallVec<[AllowlistSource; 4]>,
}

Available on crate feature http only.

A single entry in a PermissionsPolicy: pairs a feature name with the origins allowed to use it.

Construct via Self::deny, Self::allow, or Self::allow_from — those are the three shapes the spec actually defines.

Note: the PermissionsPolicy struct itself has per-feature with_deny_* / set_deny_* shortcuts for the deny-all case (the overwhelmingly common one); reach for these constructors when you need an actual allow-list.

Fields

name: PermissionsPolicyDirectiveName

allow_list: SmallVec<[AllowlistSource; 4]>

Empty allow-list serialises to name=() — the deny-all form. The W3C spec has no None allow-list state, so the deny-all directive is just an empty list.

Implementations

impl PermissionsPolicyDirective

pub fn deny( name: impl Into<PermissionsPolicyDirectiveName>, ) -> PermissionsPolicyDirective

Deny-all directive: name=().

pub fn allow( name: impl Into<PermissionsPolicyDirectiveName>, source: AllowlistSource, ) -> PermissionsPolicyDirective

Single-source allow-list: name=(source).

pub fn allow_from( name: impl Into<PermissionsPolicyDirectiveName>, sources: impl IntoIterator<Item = AllowlistSource>, ) -> PermissionsPolicyDirective

Multi-source allow-list: name=(src1 src2 …).

Trait Implementations

impl Clone for PermissionsPolicyDirective

fn clone(&self) -> PermissionsPolicyDirective

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PermissionsPolicyDirective

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

Formats the value using the given formatter.

impl Display for PermissionsPolicyDirective

impl Eq for PermissionsPolicyDirective

impl Hash for PermissionsPolicyDirective

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 PermissionsPolicyDirective

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