Struct SignalAttributes 

pub struct SignalAttributes {
    pub charge_state: i32,
    pub peptide_id: i32,
    pub isotope_peak: i32,
    pub fragment_kind: Option<FragmentType>,
    pub fragment_ordinal: Option<i32>,
}

Fields

charge_state: i32

peptide_id: i32

isotope_peak: i32

fragment_kind: Option<FragmentType>

Fragment-ion kind (b/y/…) this peak originates from, when known. Stored as a small Copy enum rather than baked into a per-peak string, which is what makes the annotated builder cheap while keeping the peak’s full fragment identity (see description).

fragment_ordinal: Option<i32>

1-based fragment-ion ordinal (the ion number, e.g. 5 for b5/y5), when known.

Implementations

impl SignalAttributes

pub fn description(&self) -> Option<String>

Human-readable fragment label "{kind}_{ordinal}_{isotope}" (e.g. b_5_1), derived on demand from the structured fields. Returns None unless both the fragment kind and ordinal are known. This reproduces the string that used to be eagerly allocated per peak, without paying for it during frame building.

Trait Implementations

impl Clone for SignalAttributes

fn clone(&self) -> SignalAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignalAttributes

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

Formats the value using the given formatter.
