Struct CryptoRule
pub struct CryptoRule {
pub cookie_names: Vec<String>,
pub algorithm: CryptoAlgorithm,
pub key: Key,
pub fallbacks: Vec<FallbackConfig>,
}Expand description
CryptoRule specifies whether certain cookies should be encrypted or signed.
Fields§
The names of the cookies to which this rule applies.
algorithm: CryptoAlgorithmHow the cookies should be secured: either encryption or signing.
key: KeyThe key to use for encryption or signing.
§Requirements
The key must be at least 64 bytes long and should be generated using a cryptographically secure random number generator.
fallbacks: Vec<FallbackConfig>Fallbacks are used to decrypt/verify request cookies that failed to be decrypted/verified using the primary key. Fallbacks are never used to encrypt/sign response cookies.
§Key rotation
Fallbacks exist to enable key and algorithm rotation.
From time to time, you may want to change the key used to sign or encrypt cookies, or update
the algorithm.
If you do this naively
(e.g. change CryptoRule::key or CryptoRule::algorithm to a new value),
the server will immediately start rejecting all existing cookies
because they were signed/encrypted with the old key/algorithm.
With fallbacks, you can start using the new configuration without invalidating all existing cookies. The process for key rotation goes as follows:
- Generate a new key
- Set
keyto the new key, and add the old key to thefallbacksvector, using the same algorithm - Wait for the expiration of all cookies signed/encrypted with the old key
- Remove the old key from the
fallbacksvector

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
