Source 
pub fn bisection<F>(
    f: F,
    lower: f64,

Expand description

Finds a root with the bisection method on a bracketing interval.

The endpoint values must have opposite signs, unless an endpoint is already approximately zero. The interval bounds and function values must be finite. Convergence uses RootOptions::tolerance as an absolute tolerance.
