Trait UlidGenerator 

pub trait UlidGenerator<ID, T, R>
where
    ID: UlidId,
    T: TimeSource<ID::Ty>,
    R: RandSource<ID::Ty>,
{
    type Err: Debug;

    // Required methods
    fn new(time: T, rng: R) -> Self;
    fn next_id(&self) -> IdGenStatus<ID>;
    fn try_next_id(&self) -> Result<IdGenStatus<ID>, Self::Err>;
}

Available on crate feature ulid only.

A minimal interface for generating Ulid IDs

Required Associated Types

type Err: Debug

Required Methods

fn new(time: T, rng: R) -> Self

fn next_id(&self) -> IdGenStatus<ID>

Returns the next available ID

fn try_next_id(&self) -> Result<IdGenStatus<ID>, Self::Err>

A fallible version of Self::next_id that returns a Result.

Errors

• May return an error if the underlying generator uses a lock and it is poisoned.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
