Expand description

The SameSite cookie attribute.

A cookie with a SameSite attribute is imposed restrictions on when it is sent to the origin server in a cross-site request. If the SameSite attribute is “Strict”, then the cookie is never sent in cross-site requests. If the SameSite attribute is “Lax”, the cookie is only sent in cross-site requests with “safe” HTTP methods, i.e, GET, HEAD, OPTIONS, TRACE. If the SameSite attribute is “None”, the cookie is sent in all cross-site requests if the “Secure” flag is also set, otherwise the cookie is ignored. This library automatically sets the “Secure” flag on cookies when same_site is set to SameSite::None as long as secure is not explicitly set to false.

If the SameSite attribute is not present (by not setting SameSite initally or passing None to Cookie::set_same_site()), then the cookie will be sent as normal.

Note: This cookie attribute is an HTTP draft! Its meaning and definition are subject to change.

Variants§

§

Strict

The “Strict” SameSite attribute.

§

Lax

The “Lax” SameSite attribute.

§

None

The “None” SameSite attribute.

Implementations§

source§

impl SameSite

source

pub fn is_strict(&self) -> bool

Returns true if self is SameSite::Strict and false otherwise.

§Example
use cookie::SameSite;

let strict = SameSite::Strict;
assert!(strict.is_strict());
assert!(!strict.is_lax());
assert!(!strict.is_none());
source

pub fn is_lax(&self) -> bool

Returns true if self is SameSite::Lax and false otherwise.

§Example
use cookie::SameSite;

let lax = SameSite::Lax;
assert!(lax.is_lax());
assert!(!lax.is_strict());
assert!(!lax.is_none());
source

pub fn is_none(&self) -> bool

Returns true if self is SameSite::None and false otherwise.

§Example
use cookie::SameSite;

let none = SameSite::None;
assert!(none.is_none());
assert!(!none.is_lax());
assert!(!none.is_strict());
