Struct VarId 

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

Stable identifier of a Var.

IDs are version-4 UUIDs. The wrapper exists so that callers cannot accidentally confuse a VarId with a crate::model::ProjectId.

Examples

use evault_core::model::VarId;

let a = VarId::new_v4();
let b = VarId::new_v4();
assert_ne!(a, b);

Implementations

impl VarId

pub fn new_v4() -> Self

Generate a fresh identifier using Uuid::new_v4.

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

Wrap an existing Uuid without generating a new one.

Use this when reconstructing a record from a backend that already has the id (e.g. a database row).

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

Borrow the inner Uuid.

Trait Implementations

impl Clone for VarId

fn clone(&self) -> VarId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VarId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VarId

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

Formats the value using the given formatter.

impl Hash for VarId

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 VarId

fn eq(&self, other: &VarId) -> 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 Serialize for VarId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for VarId
