Struct Exons 

pub struct Exons {
    pub exons: Vec<Interval>,
}

Represents a collection of exons, which are contiguous regions within genomic sequences.

Exons are the parts of a gene’s DNA that code for proteins, and they’re separated by non-coding regions called introns. This structure stores a collection of exons as intervals.

Fields

• exons - A vector of intervals representing the positions of exons within a genomic sequence.

Fields

exons: Vec<Interval>

Implementations

impl Exons

pub fn builder() -> ExonsBuilder

Create an instance of Exons using the builder syntax

impl Exons

Methods for working with exon structures.

Methods

• introns() - Calculates the intron intervals between exons
• is_empty() - Checks if there are no exons
• len() - Returns the number of exons
• span() - Calculates the total number of bases covered by all exons
• first_exon() - Gets a reference to the first exon
• last_exon() - Gets a reference to the last exon

Panics

• first_exon() will panic if there are no exons
• last_exon() will panic if there are no exons

pub fn introns(&self) -> Vec<Interval>

Returns a vector of intervals representing introns.

Introns are the regions between consecutive exons. For each pair of adjacent exons, an intron is created starting at the position immediately after the end of the first exon and ending at the position immediately before the start of the second exon.

Returns

A Vec<Interval> containing all introns between exons in this structure.

pub fn is_empty(&self) -> bool

Checks if the exon collection is empty.

Returns

true if there are no exons, false otherwise.

pub fn len(&self) -> usize

Returns the number of exons.

Returns

The count of exons as a usize.

pub fn span(&self) -> usize

Calculates the total span (combined length) of all exons.

The span is computed by summing the lengths of all intervals, where each interval length is calculated as end - start + 1.

Returns

The total span as a usize.

pub fn first_exon(&self) -> &Interval

Returns a reference to the first exon.

Panics

Panics if the exon collection is empty.

Returns

A reference to the first Interval in the exon collection.

pub fn last_exon(&self) -> &Interval

Returns a reference to the last exon.

Panics

Panics if the exon collection is empty.

Returns

A reference to the last Interval in the exon collection.
