Struct KeyVersion 

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

Key version for backward compatibility and migration. Allows different key formats to coexist during transitions.

Version 0 represents no explicit version (backward compatible with existing keys). Format: prefix{sep}env{sep}base64[.checksum]

Versions 1+ will have version between prefix and environment: Format: prefix{sep}v{N}{sep}env{sep}base64[.checksum]

Implementations

impl KeyVersion

pub const NONE: Self

No version in key Format: prefix-env-data.checksum

pub const V1: Self

Version 1 - First versioned format Format: prefix-v1-env-data.checksum

pub const V2: Self

Version 2 Format: prefix-v2-env-data.checksum

pub const fn new(version: u32) -> Self

Creates a new key version with the given number

pub const fn number(&self) -> u32

Returns the version number

pub const fn is_versioned(&self) -> bool

Returns true if this version should be included in the key

pub fn component(&self) -> String

Returns the version component string for key generation Returns empty string for version 0 (backward compatibility)

Trait Implementations

impl Clone for KeyVersion

fn clone(&self) -> KeyVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyVersion

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

Formats the value using the given formatter.

impl Default for KeyVersion

fn default() -> Self

Returns the “default value” for a type.

impl Display for KeyVersion

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

Formats the value using the given formatter.

impl Hash for KeyVersion

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KeyVersion

fn cmp(&self, other: &KeyVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for KeyVersion

fn eq(&self, other: &KeyVersion) -> 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 PartialOrd for KeyVersion

fn partial_cmp(&self, other: &KeyVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
