Supported Operations

Boolean
The list of supported operations by the homomorphic Booleans is:
Operation Name
type
not
Unary
and
Binary
or
Binary
xor
Binary
nor
Binary
xnor
Binary
cmux
Ternary
A walk-through using homomorphic Booleans can be found here.
ShortInt
In TFHE-rs, shortint represents short unsigned integers encoded over a maximum of 8 bits. A complete homomorphic arithmetic is provided, along with the possibility to compute univariate and bi-variate functions. Some operations are only available for integers up to 4 bits. More technical details can be found here.
The list of supported operations is:
Operation name

Negation
Unary
Addition

Subtraction
Binary
Multiplication
Binary
Division*
Binary
Modular reduction
Binary
Comparisons
Binary
Left/Right Shift
Binary
And
Binary
Or
Binary
Xor

Unary/Binary
* The division operation implements a subtlety: since data is encrypted, it might be possible to compute a division by 0. In this case, the division is tweaked so that dividing by 0 returns 0.
A walk-through example can be found here, and more examples and explanations can be found here.
