Struct KeyDerivationParams 

pub struct KeyDerivationParams {
    pub salt: [u8; 16],
    pub iterations: u32,
}

Parameters for deriving an encryption key from a user-supplied secret.

Architectural intent: Encapsulates the tunable inputs for PBKDF2-based key derivation so that snapshot metadata fully describes how to reproduce the encryption key on restore.

Constraints: salt must be unique per snapshot to avoid key reuse, and iterations is chosen to be intentionally expensive (hundreds of thousands of rounds) to raise the cost of offline brute-force attacks while remaining acceptable for interactive CLI usage.

Side effects: Instances produced via Default consume randomness from the process RNG and implicitly fix the work factor at the compile-time constant embedded in this type.

Fields

salt: [u8; 16]

iterations: u32

Trait Implementations

impl Clone for KeyDerivationParams

fn clone(&self) -> KeyDerivationParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeyDerivationParams

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

Formats the value using the given formatter.

impl Default for KeyDerivationParams

fn default() -> Self

Generates key-derivation parameters for a new snapshot.

Architectural intent: Produces a fresh random salt and a stable iteration count that all writers and readers agree on, so that keys can be recomputed deterministically from the password and stored metadata.

Constraints: The salt is 128 bits and sampled uniformly from the system RNG; the iteration count is fixed to a value calibrated for this application and must be kept in sync with password prompts.

Side effects: Pulls entropy from rand::thread_rng and performs no I/O; increasing the iteration count will linearly increase CPU cost for both snapshot creation and decryption.

impl<'de> Deserialize<'de> for KeyDerivationParams

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for KeyDerivationParams

fn eq(&self, other: &KeyDerivationParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for KeyDerivationParams

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
