Struct UserId 

pub struct UserId(pub u64);

A user’s id. Apps convert to and from their own u64 ids with new and get or From, and to and from signed integers with TryFrom, which fails on a value out of the other’s range. With the sqll015 feature it binds and reads as a sqll column directly.

Tuple Fields

0: u64

Implementations

impl UserId

pub const fn new(id: u64) -> Self

The id with the given value.

pub const fn get(self) -> u64

The id’s value.

Trait Implementations

impl Bind for UserId

Available on crate feature sqll015 only.

Binds as the statement’s only parameter, as BindValue does.

const COUNT: usize = 1

The number of parameters that this binding binds.

fn bind(&self, stmt: &mut Statement) -> Result<()>

Bind this value into the given Statement.

impl BindValue for UserId

Available on crate feature sqll015 only.

Binds as an SQLite integer with the same bits, so an INTEGER PRIMARY KEY holds every id a store assigns: every id binds, and one beyond i64::MAX binds as a negative integer that no stored user has.

fn bind_value(&self, stmt: &mut Statement, index: Index) -> Result<()>

Bind a value to the specified parameter index.

impl Clone for UserId

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 UserId

Formats the value using the given formatter.

impl<'__de, __A> Decode<'__de, Binary, __A> for UserId

where __A: Allocator,

impl<'__de, __A> Decode<'__de, Text, __A> for UserId

where __A: Allocator,

Available on crate feature musli02 only.

const IS_BITWISE_DECODE: bool = false

Whether the type is packed. Packed types can be bitwise copied if the representation of the serialization format is identical to the memory layout of the type.

fn decode<T0>(_1: T0) -> Result<Self, <T0 as Decoder<'__de>>::Error>

impl Display for UserId

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

Formats the value using the given formatter.

impl Encode<Binary> for UserId

Available on crate feature musli02 only.

const IS_BITWISE_ENCODE: bool = false

type Encode = UserId

The underlying type being encoded.

fn encode<T0>(&self, _0: T0) -> Result<(), <T0 as Encoder>::Error>

where T0: Encoder<Mode = Binary>,

where T0: Encoder<Mode = Text>,

Encode the given output.
