Enum SolveFailure 

pub(crate) enum SolveFailure {
    Unbracketed {
        lo: f64,
        hi: f64,
    },
    Unconverged {
        residual: f64,
        iterations: usize,
    },
}

Why a solve did not produce a root.

Variants

Unbracketed

f(lo) and f(hi) sit on the same side of the target.

Fields

lo: f64

hi: f64

Unconverged

The iteration cap was reached with this residual outstanding.

Fields

residual: f64

iterations: usize

Trait Implementations

impl Clone for SolveFailure

fn clone(&self) -> SolveFailure

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SolveFailure

impl Debug for SolveFailure

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SolveFailure

fn eq(&self, other: &SolveFailure) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
