Struct CartId 

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

Strongly-typed shopping cart identifier.

Implementations

impl CartId

pub fn new() -> CartId

Available on crate feature std only.

Create a new random ID (UUID v4).

pub const fn nil() -> CartId

Create a nil (all-zeros) ID.

pub const fn from_uuid(id: Uuid) -> CartId

Create from an existing Uuid.

pub const fn as_uuid(&self) -> &Uuid

Get the inner Uuid.

pub const fn into_uuid(self) -> Uuid

Consume and return the inner Uuid.

pub const fn is_nil(&self) -> bool

Returns true if this is a nil (all-zeros) ID.
