Struct FailureContext 

#[non_exhaustive]
pub struct FailureContext {
    pub key_name: String,
    pub consecutive_failures: u32,
    pub window_elapsed: Duration,
    pub note: Cow<'static, str>,
}

Context passed when a decryption attempt fails — wrong key, tampered ciphertext, etc.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key_name: String

Logical name of the key whose use produced the failure.

consecutive_failures: u32

Number of consecutive failures observed for this key, including this one.

window_elapsed: Duration

Time elapsed since the first failure in the current window.

note: Cow<'static, str>

Caller-supplied free-form note. Sanitized — never includes key bytes or ciphertext.
