Struct ciphercore_base::ops::comparisons::Equal

pub struct Equal {}

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

If a and b are two bitstrings, then Equal(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 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 Equal 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(Equal {}), vec![n1, n2]).unwrap();

Trait Implementations

impl CustomOperationBody for Equal

fn instantiate(
    &self,
    context: Context,
    arguments_types: Vec<Type>
) -> Result<Graph>

Defines the logic of a custom operation.

fn get_name(&self) -> String

Specifies and returns the name of this custom operation.

impl Debug for Equal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Equal

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>,
