Struct ProteusPrekey 

pub struct ProteusPrekey {
    pub id: u16,
    pub prekey: Vec<u8>,
}

Entity representing a stored Proteus prekey.

This entity cannot be updated in the DB. A prekey id is published to peers in a prekey bundle, and overwriting the prekey it names would leave those peers holding a bundle no session can be established from. A save under an id which is already taken therefore reports CryptoKeystoreError::AlreadyExists rather than replacing the stored prekey.

Fields

id: u16

prekey: Vec<u8>

Implementations

impl ProteusPrekey

pub fn from_raw(id: u16, prekey: Vec<u8>) -> Self

pub fn get_free_id(conn: &Connection) -> CryptoKeystoreResult<u16>

Get the lowest free prekey id.

Ids freed by deletion are handed out before the id space is extended.

Returns CryptoKeystoreError::NoFreePrekeyId if every assignable id is taken.

Trait Implementations

impl Clone for ProteusPrekey

fn clone(&self) -> ProteusPrekey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProteusPrekey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProteusPrekey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Entity for ProteusPrekey

const TABLE_NAME: &'static str = "proteus_prekeys"

The name of the SQL table for this entity

fn get(conn: &Connection, key: &u16) -> CryptoKeystoreResult<Option<Self>>

Get an entity by its primary key.

fn count(conn: &Connection) -> CryptoKeystoreResult<u32>

Count the number of entities of this type in the database.

fn load_all(conn: &Connection) -> CryptoKeystoreResult<Vec<Self>>

Retrieve all entities of this type from the database.

impl EntityDatabaseMutation for ProteusPrekey

fn save<'a, Tx>(&self, tx: &'a Tx) -> CryptoKeystoreResult<()>

where &'a Tx: Into<Transactionlike<'a>>,

Save this entity to the database in the context of this transaction.

fn delete<'a, Tx>(tx: &'a Tx, id: &u16) -> CryptoKeystoreResult<bool>

where &'a Tx: Into<Transactionlike<'a>>,

Use the transaction’s inteface to delete this entity from the database.

impl PartialEq for ProteusPrekey

fn eq(&self, other: &ProteusPrekey) -> 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 PrimaryKey for ProteusPrekey

type PrimaryKey = u16

Each distinct PrimaryKey uniquely identifies either 0 or 1 instance.

fn primary_key(&self) -> u16

Get this entity’s primary key.

impl Serialize for ProteusPrekey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToValue for ProteusPrekey

fn to_value(&self) -> Value<'_>

Perform the conversion.

impl Zeroize for ProteusPrekey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Eq for ProteusPrekey
