pub struct HmacEnvelope<K>where
K: KeyProvider,{ /* private fields */ }Expand description
HMAC-SHA-256 backed envelope. Sealed messages are self-describing
CBOR maps: signature recipients can decode the envelope, fetch the
key by kid, and verify without out-of-band coordination.
Implementations§
Source§impl<K> HmacEnvelope<K>where
K: KeyProvider,
impl<K> HmacEnvelope<K>where
K: KeyProvider,
pub fn new(keys: Arc<K>, signing_kid: impl Into<String>) -> HmacEnvelope<K>
pub fn with_clock_skew_secs(self, secs: i64) -> HmacEnvelope<K>
Sourcepub fn with_nonce_store(self, store: Arc<dyn NonceStore>) -> HmacEnvelope<K>
pub fn with_nonce_store(self, store: Arc<dyn NonceStore>) -> HmacEnvelope<K>
Attach a nonce store so open rejects replays. Without this,
the envelope is only protected by the clock-skew window — an
attacker who captured a sealed message can replay it inside
that window.
Sourcepub async fn seal(&self, payload: Value) -> Result<SealedEnvelope, CoolError>
pub async fn seal(&self, payload: Value) -> Result<SealedEnvelope, CoolError>
Seal a request body. The returned bytes are a CBOR-encoded
SealedEnvelope payload — the sender wraps these in their
codec of choice on the way out.
Sourcepub async fn open(&self, envelope: &SealedEnvelope) -> Result<Value, CoolError>
pub async fn open(&self, envelope: &SealedEnvelope) -> Result<Value, CoolError>
Verify a sealed envelope. Returns the body on success. Constant- time MAC compare; clock-skew window enforced; envelope kid is resolved through the configured provider so callers can rotate keys without changing the recipient.

Source§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().

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().

Source§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();Source§fn rapid_blink(&self) -> 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();Source§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.

The clear() method will be removed in a future release.
Source§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);
