Struct OpenOptions

Source

pub struct OpenOptions {
    pub parallel: i64,
    pub zoom_correction: f64,
    pub block_size: Option<u64>,
    pub max_blocks: Option<usize>,
    pub index_path: Option<String>,
}

Expand description

Everything open takes beyond the path.

None on a buffer field means “recommended”, which is what -1 spells in the Python API — and the recommendation differs by source: 32 KiB blocks for a local file, 1 MiB for a URL, 128 blocks either way.

Fields§

§parallel: i64

Worker threads. Zero or less means one per core, capped at 12.

§zoom_correction: f64

bigWig only: scaling factor for automatic zoom selection.

§block_size: Option<u64>§max_blocks: Option<usize>§index_path: Option<String>

BAM only. Defaults to the file’s path with .bai appended.
