 To use elliptic curve operations on a struct defined with `sw_declare!` or `te_declare!`, it is expected that the struct for the curve's coordinate field was defined using `moduli_declare!`. In particular, the coordinate field needs to be initialized and set up as described in the [algebra extension](./algebra.md) chapter.
