Struct MasterKey 

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

The vault master key (32 bytes), held in protected memory.

Zeroized on drop, redacted Debug, and — like crate::SecretValue — has no Display and is not serializable. The bytes are reachable only via MasterKey::expose, for handing to crate::seal/crate::open.

Implementations

impl MasterKey

pub fn new(bytes: [u8; 32]) -> Self

Wrap raw key bytes.

pub fn expose(&self) -> &[u8; 32]

Borrow the key bytes. Use deliberately — this is the one path out.

Trait Implementations

impl Debug for MasterKey

Redacted Debug: never reveals key material (I12). No Display impl exists.

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

Formats the value using the given formatter.

impl Drop for MasterKey

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
