Struct Centroided 

pub struct Centroided<S: SpectrumSource> { /* private fields */ }

Wraps a SpectrumSource, centroiding every profile-mode spectrum it yields. Spectra already tagged ScanMode::Centroid pass through unchanged (idempotent).

Implementations

impl<S: SpectrumSource> Centroided<S>

pub fn new(inner: S) -> Self

Wrap inner, picking every local-maximum peak regardless of height.

pub fn with_min_intensity(self, min_intensity: f32) -> Self

Discard picked peaks below min_intensity (a simple noise floor).

Trait Implementations

impl<S: SpectrumSource> SpectrumSource for Centroided<S>

fn run_metadata(&self) -> RunMetadata

Run-level metadata. Cheap to call; vendors typically build this once.

fn iter_spectra<'a>( &'a mut self, ) -> Box<dyn Iterator<Item = SpectrumRecord> + 'a>

Iterate every spectrum the file contains. Spectra the parser cannot decode should be skipped silently; the writer trusts whatever the iterator yields.

fn iter_chromatograms<'a>( &'a mut self, ) -> Box<dyn Iterator<Item = ChromatogramRecord> + 'a>

Iterate chromatogram traces (TIC, BPC, SRM). Defaults to an empty iterator; most parsers do not synthesize chromatograms.

fn spectrum_count_hint(&self) -> Option<usize>

Total number of spectra the source will yield, when known cheaply. Used by the mzML writer to populate <spectrumList count="...">. If None, the writer falls back to buffering spectrum offsets and patching the count at the end.
