Struct Region 

pub struct Region {
    pub chr: String,
    pub start: u32,
    pub end: u32,
    pub rest: Option<String>,
}

Region struct, representation of one Region in RegionSet files

Fields

chr: String

start: u32

end: u32

rest: Option<String>

Implementations

impl Region

pub fn width(&self) -> u32

Get length of the file

pub fn as_string(&self) -> String

Get file string of Region

pub fn digest(&self) -> String

Calculate digest for the Region

pub fn mid_point(&self) -> u32

Calculate the midpoint of this region: start + width / 2.

NOTE: R’s GenomicDistributions computes midpoints using banker’s rounding in 1-based coordinates: start + round((end - start) / 2). For regions with width ≡ 2 (mod 4), this picks the left-of-center base while our formula picks right-of-center, causing a ±1 bp difference in ~2.6% of feature distance calculations. This is a known discrepancy; to match GD exactly, change the formula to: if w % 4 == 2 { start + w/2 - 1 } else { start + w/2 }.

pub fn mid_point_with_mode(&self, mode: CoordinateMode) -> u32

Calculate midpoint using the specified coordinate convention.

• Bed (default): floor division → start + width / 2
• GRanges: banker’s rounding in 1-based coords → if w % 4 == 2 { start + w/2 - 1 } else { start + w/2 }

pub fn distance_to(&self, other: &Region) -> i64

Gap distance between two regions.

Returns 0 if the regions overlap, otherwise returns the positive gap (in bases) between the closer edges of the two regions.
