Struct ciphercore_base::ops::comparisons::LessThan

pub struct LessThan {
    pub signed_comparison: bool,
}

A structure that defines the custom operation LessThan that compares arrays of binary strings elementwise as follows:

If a and b are two bitstrings, then LessThan(a,b) = 1 if a < b and 0 otherwise.

The last dimension of both inputs must be the same; it defines the length of input bitstrings. If input shapes are different, the broadcasting rules are applied (see the NumPy broadcasting rules). For example, if input arrays are of shapes [2,3], and [1,3], the resulting array has shape [2].

To compare signed numbers, signed_comparison should be set true.

To use this and other custom operations in computation graphs, see Graph::custom_op.

Custom operation arguments

• Node containing a binary array or scalar
• Node containing a binary array or scalar

Custom operation returns

New LessThan node

Example

let c = create_context().unwrap();
let g = c.create_graph().unwrap();
let t = array_type(vec![2, 3], BIT);
let n1 = g.input(t.clone()).unwrap();
let n2 = g.input(t.clone()).unwrap();
let n3 = g.custom_op(CustomOperation::new(LessThan {signed_comparison: true}), vec![n1, n2]).unwrap();

Fields

signed_comparison: bool

Boolean value indicating whether input bitstring represent signed integers
