Enum Tolerance 

#[non_exhaustive]
pub enum Tolerance {
    High,
    Medium,
    Fast,
    Custom(f64),
}

Convergence accuracy level.

Abstracts the raw ipm.eps field. When set on SolverOptions, the solver derives its internal convergence threshold from this enum; ipm.eps is ignored.

Translation table

Tolerance	IPM eps
High	TOLERANCE_HIGH_EPS = 1e-8
Medium	TOLERANCE_MEDIUM_EPS = 1e-6
Fast	TOLERANCE_FAST_EPS = 1e-4
Custom(v)	v

Medium is the default (comparable to Gurobi eps = 1e-6). Fast accepts solutions 100× less precise than Medium for reduced iteration counts — appropriate when a coarse objective estimate suffices.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

High

High accuracy: research / verification workloads.

Medium

Medium accuracy (default): general-purpose workloads.

Fast

Fast: speed-priority, looser convergence (100× coarser than Medium).

Custom(f64)

Custom: pass the eps value directly to each solver.

Trait Implementations

impl Clone for Tolerance

fn clone(&self) -> Tolerance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tolerance

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

Formats the value using the given formatter.

impl PartialEq for Tolerance

fn eq(&self, other: &Tolerance) -> 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.

impl Copy for Tolerance

impl StructuralPartialEq for Tolerance
