Struct MockUuid 

pub struct MockUuid { /* private fields */ }

Mock UUID provider for testing.

Can generate sequential UUIDs or return predetermined values.

Implementations

impl MockUuid

pub fn sequential() -> Self

Create a mock UUID provider that generates sequential UUIDs.

The first UUID will be 00000000-0000-0000-0000-000000000001.

Example

use xerv_core::testing::MockUuid;
use xerv_core::testing::UuidProvider;

let provider = MockUuid::sequential();
let id1 = provider.new_v4();
let id2 = provider.new_v4();

assert_eq!(id1.to_string(), "00000000-0000-0000-0000-000000000001");
assert_eq!(id2.to_string(), "00000000-0000-0000-0000-000000000002");

pub fn sequential_from(start: u64) -> Self

Create a mock UUID provider that generates sequential UUIDs starting at the given value.

pub fn predetermined(uuids: Vec<Uuid>) -> Self

Create a mock UUID provider that returns predetermined UUIDs.

UUIDs are returned in the order provided. If more UUIDs are requested than provided, sequential UUIDs are generated starting from 1.

Example

use xerv_core::testing::MockUuid;
use xerv_core::testing::UuidProvider;
use uuid::Uuid;

let id = Uuid::parse_str("12345678-1234-1234-1234-123456789abc").unwrap();
let provider = MockUuid::predetermined(vec![id]);

assert_eq!(provider.new_v4(), id);
// Next call returns sequential UUID (starting from 1)
assert_eq!(provider.new_v4().to_string(), "00000000-0000-0000-0000-000000000001");

pub fn from_strings(uuids: &[&str]) -> Self

Create a mock UUID provider from string representations.

Panics

Panics if any string is not a valid UUID.

pub fn current_counter(&self) -> Option<u64>

Get the current sequential counter value (for debugging).

Trait Implementations

impl UuidProvider for MockUuid

fn new_v4(&self) -> Uuid

Generate a new UUID.

fn is_mock(&self) -> bool

Check if this is a mock provider.
