Struct rust_lapper::Lapper

pub struct Lapper<T: Eq + Clone> {
    pub intervals: Vec<Interval<T>>,
    // some fields omitted
}

Primary object of the library. The public intervals holds all the intervals and can be used for iterating / pulling values out of the tree.

Fields

intervals: Vec<Interval<T>>

Methods

impl<T: Eq + Clone> Lapper<T>

pub fn new(intervals: Vec<Interval<T>>) -> Self

pub fn len(&self) -> usize

Get the number over intervals in Lapper

pub fn cov(&self) -> usize

Get the number of positions covered by the intervals in Lapper. This provides immutable access if it has already been set, or on the fly calculation.

pub fn set_cov(&mut self) -> usize

Get the number fo positions covered by the intervals in Lapper and store it. If you are going to be using the coverage, you should set it to avoid calculating it over and over.

Important traits for IterLapper<'a, T>

impl<'a, T: Eq + Clone> Iterator for IterLapper<'a, T> type Item = &'a Interval<T>;

pub fn iter<'a>(&'a self) -> IterLapper<'a, T>

Return an iterator over the intervals in Lapper

pub fn merge_overlaps(&mut self)

Merge any intervals that overlap with eachother within the Lapper

Important traits for IterFind<'a, T>

impl<'a, T: Eq + Clone> Iterator for IterFind<'a, T> type Item = &'a Interval<T>;

pub fn find<'a>(&'a self, start: usize, stop: usize) -> IterFind<'a, T>

Find all intervals that overlap start .. stop

Important traits for IterFind<'a, T>

impl<'a, T: Eq + Clone> Iterator for IterFind<'a, T> type Item = &'a Interval<T>;

pub fn seek<'a>(
    &'a self,
    start: usize,
    stop: usize,
    cursor: &mut usize
) -> IterFind<'a, T>

Find all intevals that overlap start .. stop. This method will work when queries to this lapper are in sorted (start) order. It uses a linear search from the last query instead of a binary search. A reference to a cursor must be passed in. This reference will be modified and should be reused in the next query. This allows seek to not need to make the lapper object mutable, and thus use the same lapper accross threads.
