TfheRustBool

’tfhe_rust_bool’ Dialect

The tfhe_rust_bool dialect is an exit dialect for generating rust code against the tfhe-rs library API, using the boolean parameter set.

TfheRustBool attributes

TfheRustBoolGatesAttr

An Attribute containing an array of strings to store bool gates

Syntax:

#tfhe_rust_bool.tfhe_rust_bool_gates<
  ::llvm::ArrayRef<::mlir::heir::tfhe_rust_bool::TfheRustBoolGateEnumAttr>   # gates
>

This attributes stores a list of integer identifiers for Boolean gates.

Uses following mapping: AND_GATE = 0; NAND_GATE = 1; OR_GATE = 2; NOR_GATE = 3; XOR_GATE = 4; XNOR_GATE = 5; NOT_GATE = 6;

Parameters:

TfheRustBool types

EncryptedBoolType

An encrypted Boolean corresponding to tfhe-rs’s FHEBool type

Syntax: !tfhe_rust_bool.eb

PackedServerKeyType

The Belfort packed API boolean server key.

Syntax: !tfhe_rust_bool.server_key_enum

ServerKeyType

The boolean server key required to perform homomorphic operations.

Syntax: !tfhe_rust_bool.server_key

tfhe_rust_bool.gates_packed (heir::tfhe_rust_bool::PackedOp)

Syntax:

operation ::= `tfhe_rust_bool.gates_packed` operands attr-dict `:` functional-type(operands, results)

Operation to where different Boolean gates are executed pairwise between elements of two ciphertext arrays.

For example,

%0 = tfhe_rust_bool.packed_gates %a, %b {gates = #tfhe_rust_bool.tfhe_rust_bool_gates<0 : i32, 4 : i32>} :
    (!tfhe_rust_bool.server_key,
     tensor<2x!tfhe_rust_bool.eb>,
     tensor<2x!tfhe_rust_bool.eb>) -> tensor<2x!tfhe_rust_bool.eb>

applies an “and” gate to the first elements of %a and %b and an xor gate to the second elements.

Mapping is defined in the BooleanGates.td file.
