Trait EntropySource 

pub trait EntropySource: Send {
    // Required methods
    fn timestamp(&mut self) -> Option<u64>;
    fn random(&mut self, range: RangeInclusive<u128>) -> Option<u128>;
}

Trait for entropy sources.

For a type to be used as an entropy source, implement the EntropySource trait and create an EntropySourceHandle out of it and set the handle using the set_entropy_source function.

Example

struct MySource;

impl MySource {
    fn new() -> Self {
        todo!()
    }
}

impl mr_ulid::EntropySource for MySource {
    fn timestamp(&mut self) -> Option<u64> {
        todo!()
    }
    fn random(&mut self, range: std::ops::RangeInclusive<u128>) -> Option<u128> {
        todo!()
    }
}

let my_source = MySource::new();
let handle = mr_ulid::EntropySourceHandle::new(my_source);

mr_ulid::set_entropy_source(handle);

Required Methods

fn timestamp(&mut self) -> Option<u64>

Returns the current timestamp in milliseconds since the Unix epoch.

fn random(&mut self, range: RangeInclusive<u128>) -> Option<u128>

Returns a random number in the given range.
