Enum CryptScheme 

pub enum CryptScheme {
    Native,
    Php,
}

Which payload envelope this application writes.

Selected by APP_CIPHER, and deliberately a closed set: writing the wrong envelope is not a preference that degrades gracefully, it is a column nothing can read.

use rainier_crypt::CryptScheme;
use rainier_support::Setting;

assert_eq!(CryptScheme::parse("php").unwrap(), CryptScheme::Php);
assert!(CryptScheme::parse("hpp").is_err());

Variants

Native

Rainier’s own: a self-describing, URL-safe payload naming its algorithm and its key.

The default, and what a new application wants — rotation and a cipher change are both possible without re-encrypting anything.

Php

The {iv, value, mac} envelope, for a database PHP already wrote.

A migration position, not a destination — see the module docs.

Implementations

impl CryptScheme

pub fn as_str(&self) -> &'static str

The wire spelling — what appears in .env and in the config tree.

Inherent as well as on the trait, so callers do not have to import Setting to print one.

Trait Implementations

impl AsRef<str> for CryptScheme

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for CryptScheme

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CryptScheme

impl Debug for CryptScheme

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

Formats the value using the given formatter.

impl Default for CryptScheme

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CryptScheme

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CryptScheme

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

Formats the value using the given formatter.

impl Eq for CryptScheme

impl FromStr for CryptScheme

type Err = Error

The associated error which can be returned from parsing.

fn from_str(raw: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for CryptScheme

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 PartialEq for CryptScheme

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for CryptScheme

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Setting for CryptScheme

const SETTING: &'static str = "encryption scheme"

What this setting is called in an error message — "cache driver".

const ALL: &'static [Self]

Every variant, in the order they should be listed to a human.

fn as_str(&self) -> &'static str

The wire spelling — what appears in .env, in the config tree, and in serialised output.

fn parse(raw: &str) -> Result<Self, Error>

Parse a wire spelling.

fn options() -> String

The valid spellings, backtick-quoted and comma-separated.
