source§fn len(&self) -> u64
fn len(&self) -> u64
Get the number of values logically in the ORAM.
This is also one more than the largest index that can be legally
accessed.
source§fn stash_size(&self) -> usize
fn stash_size(&self) -> usize
Get the number of values in the ORAM’s stash for diagnostics. In prod,
this number should be viewed as secret and not revealed.
source§fn access<T, F: FnOnce(&mut A64Bytes<ValueSize>) -> T>(
&mut self,
query: u64,
f: F
) -> T
fn access<T, F: FnOnce(&mut A64Bytes<ValueSize>) -> T>( &mut self, query: u64, f: F ) -> T
Access the ORAM at a position, calling a lambda with the recovered
value, and returning the result of the lambda.
This cannot fail, but will panic if index is out of bounds. Read more
source§fn read(&mut self, index: u64) -> A64Bytes<ValueSize>
fn read(&mut self, index: u64) -> A64Bytes<ValueSize>
High-level helper – when you only need to read and don’t need to write
a new value, this is simpler than using
access.
In most ORAM there will not be a significantly faster implementation of
this.source§fn write(
&mut self,
index: u64,
new_val: &A64Bytes<ValueSize>
) -> A64Bytes<ValueSize>
fn write( &mut self, index: u64, new_val: &A64Bytes<ValueSize> ) -> A64Bytes<ValueSize>
High-level helper – when you need to write a value and want the
previous value, but you don’t need to see the previous value when
deciding what to write, this is simpler than using
access.
In most ORAM there will not be a significantly faster implementation of
this.
