Struct Origin 

pub struct Origin(/* private fields */);

The scheme-and-authority an Origin names, compared as such.

Lowercased on parse, because RFC 6454 §6.2.2 makes the comparison case-insensitive for scheme and host: a browser sends HTTP://Example.COM and a byte-comparing server refuses a page it just served. A path or query in an Origin is refused outright — the header is scheme-and-host-only, and a value carrying more is not a value this policy can reason about.

Implementations

impl Origin

pub fn as_str(&self) -> &str

The origin as sent, lowercased in its scheme and host.

pub fn host(&self) -> &str

The host this origin names, without the scheme and without the port.

Brackets are stripped, so an IPv6 host reads as ::1 rather than as [::1], which is the form every comparison in this module wants.

pub fn is_loopback(&self) -> bool

Whether this origin names the loopback interface.

Exactly localhost, 127.0.0.1 or ::1, and nothing else. This is the check that keeps a rebinding defence from rebinding: localhost is compared whole, so localhost.evil.example and 127.0.0.1.evil.example are not loopback and are not excused by this.

Trait Implementations

impl Clone for Origin

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Origin

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

Formats the value using the given formatter.

impl Eq for Origin

impl FromStr for Origin

fn from_str(value: &str) -> Result<Self, Self::Err>

Errors

OriginError::Empty for an empty value, OriginError::UnsupportedScheme for a scheme other than HTTP(S), and OriginError::NotAnOrigin for anything that is not scheme://host[:port] — including a bare host, a trailing path, or a null origin, which is what a sandboxed frame and some redirects send.

type Err = OriginError

The associated error which can be returned from parsing.

impl Hash for Origin

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Origin

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Origin

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Origin

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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