Trait ErrorModel 

pub trait ErrorModel {
    // Required method
    fn error_probability(&self, cycle: usize, read_end: ReadEnd) -> f64;

    // Provided method
    fn base_quality_phred33(&self, cycle: usize, read_end: ReadEnd) -> u8 { ... }
}

Trait for position-dependent sequencing error models.

Implementors produce an error probability for each cycle position, allowing realistic simulation of position-dependent error rates. The trait is the extensibility point for future platform support (Element, Ultima, etc.).

Required Methods

fn error_probability(&self, cycle: usize, read_end: ReadEnd) -> f64

Return the probability of a sequencing error at the given cycle position (0-based) for the given read end.

Provided Methods

fn base_quality_phred33(&self, cycle: usize, read_end: ReadEnd) -> u8

Return the Phred+33 base quality score for the given cycle and read end (before per-base noise).

The default implementation computes Q = -10*log10(p_err) clamped to [2, 41] and adds the Phred+33 offset. Implementors may override this with a precomputed lookup for speed.
