Required Methods§

Source

fn next<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the next value and increments the sequence.

Source

fn peek<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the current value stored in the remote storage without incrementing the sequence.

Source

fn jump_to<'life0, 'async_trait>( &'life0 self, next: u64, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Jumps to the given value.

Source

fn min_max<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Range<u64>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the range of available sequences.
