[−][src]Struct foundationdb::tuple::hca::HighContentionAllocator
Represents a High Contention Allocator for a given subspace
Implementations
impl HighContentionAllocator[src]
pub fn new(subspace: Subspace) -> HighContentionAllocator[src]
Constructs an allocator that will use the input subspace for assigning values. The given subspace should not be used by anything other than the allocator
pub async fn allocate<'_, '_>(
&'_ self,
trx: &'_ Transaction
) -> Result<i64, HcaError>[src]
&'_ self,
trx: &'_ Transaction
) -> Result<i64, HcaError>
Returns a byte string that
- has never and will never be returned by another call to this method on the same subspace
- is nearly as short as possible given the above
