}Expand description
Group (mathematics) that can be converted from a byte array
Into<[u8; LAMBDA]> is not used in any fss crate so not included.
But it is implemented by all groups in the submodules.
Required Methods§
sourcefn add_inverse(self) -> Self
fn add_inverse(self) -> Self
Additive inverse in the group, e.g., -x for x in the integer group
Provided Methods§
sourcefn add_inverse_if(self, t: bool) -> Self
fn add_inverse_if(self, t: bool) -> Self
Helper to get the additive inverse if true.
Used for expressions like $(-1)^n x$, in which t can be computed from n.
Object Safety§
This trait is not object safe.
