Struct InstanceId 

pub struct InstanceId(pub Uuid);

Available on crate feature sync only.

Unique identifier for a PulseDB instance (UUID v7, time-ordered).

Each PulseDB database generates an InstanceId on first open and persists it in the metadata table. This ID is used to identify the source of sync changes and track per-peer cursors.

Example

use pulsedb::sync::types::InstanceId;

let id = InstanceId::new();
println!("Instance: {}", id);
assert_eq!(id.as_bytes().len(), 16);

Tuple Fields

0: Uuid

Implementations

impl InstanceId

pub fn new() -> Self

Creates a new InstanceId with a UUID v7 (time-ordered).

pub fn nil() -> Self

Creates a nil (all zeros) InstanceId. Useful for testing or sentinel values.

pub fn as_bytes(&self) -> &[u8; 16]

Returns the raw UUID bytes for storage.

pub fn from_bytes(bytes: [u8; 16]) -> Self

Creates an InstanceId from raw bytes.

Trait Implementations

impl Clone for InstanceId

fn clone(&self) -> InstanceId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceId

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

Formats the value using the given formatter.

impl Default for InstanceId

fn default() -> Self

Returns a nil (all zeros) InstanceId.

For a new unique ID, use InstanceId::new().

impl<'de> Deserialize<'de> for InstanceId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for InstanceId

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

Formats the value using the given formatter.

impl Hash for InstanceId

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 InstanceId

fn eq(&self, other: &InstanceId) -> 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 InstanceId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
