pub struct KeyRotationManager { /* private fields */ }Expand description
Manager for coordinating key rotation across the system.
Key rotation involves:
- Creating a new master key version in the KMS
- Re-wrapping all existing DEKs with the new version
- Invalidating caches
This manager handles the orchestration while being storage-agnostic.
Implementations§
Source§impl KeyRotationManager
impl KeyRotationManager
Sourcepub fn new(kms: Arc<dyn KeyManagementService>) -> Self
pub fn new(kms: Arc<dyn KeyManagementService>) -> Self
Creates a new rotation manager.
Sourcepub async fn rotate_master_key(&self, key_id: &str) -> Result<u32>
pub async fn rotate_master_key(&self, key_id: &str) -> Result<u32>
Initiates a master key rotation.
This triggers the KMS to create a new key version. After this, all new DEKs will be wrapped with the new version.
Existing DEKs remain valid (KMS keeps old versions) but should
be re-wrapped using rewrap_deks for full forward secrecy.
Sourcepub async fn rewrap_dek(
&self,
key_id: &str,
wrapped_dek: &[u8],
) -> Result<Vec<u8>>
pub async fn rewrap_dek( &self, key_id: &str, wrapped_dek: &[u8], ) -> Result<Vec<u8>>
Re-wraps a single DEK with the current master key version.
Returns the newly wrapped DEK ciphertext.
Sourcepub async fn rewrap_deks_batch(
&self,
key_id: &str,
wrapped_deks: &[Vec<u8>],
) -> KeyRotationResult
pub async fn rewrap_deks_batch( &self, key_id: &str, wrapped_deks: &[Vec<u8>], ) -> KeyRotationResult
Re-wraps multiple DEKs in batch.
Returns results for each DEK (success or error).
Sourcepub fn is_current_version(&self, wrapped_dek: &[u8]) -> Option<bool>
pub fn is_current_version(&self, wrapped_dek: &[u8]) -> Option<bool>
Verifies a wrapped DEK is using the current master key version.
This is provider-specific and may not be available for all KMS implementations. For EnvKeyProvider, it checks the version prefix in the ciphertext.

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().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§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().

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>

Source§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();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.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
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);
