Defined in: error.rs:5
pub struct Tolerances { pub atol: f64, pub rtol: f64,}Tolerance configuration for adaptive step-size integrators.
Fields
Section titled “Fields”atol: f64
Absolute tolerance (applied uniformly to all state components).
rtol: f64
Relative tolerance (applied uniformly to all state components).
Methods
Section titled “Methods”validate()
Section titled “validate()”fn validate(&self) -> [Result<(), IntegrationError>](https://doc.rust-lang.org/std/result/enum.Result.html)
Reject tolerances that would make adaptive error control meaningless.
atol == 0 && rtol == 0 makes the scale factor sc zero, so a
component whose error is also zero yields 0 / 0 == NaN. A NaN error
norm compares false against both the accept threshold and the
dt_min floor, so the stepper would retry the same step forever.
