Struct blstrs_plus::Gt

#[repr(transparent)]
pub struct Gt(_);

This is an element of $\mathbb{G}_T$, the target group of the pairing function. As with $\mathbb{G}_1$ and $\mathbb{G}_2$ this group has order $q$.

Typically, $\mathbb{G}_T$ is written multiplicatively but we will write it additively to keep code and abstractions consistent.

Implementations

impl Gt

pub const BYTES: usize = 576usize
