Struct bam::index::VirtualOffset

pub struct VirtualOffset(_);

Virtual offset. Represents block_offset << 16 | contents_offset, where block_offset is u48 and represents the offset in the bgzip file to the beginning of th block (also known as coffset or compressed_offset).

contents_offset is u16 and represents offset in the uncompressed data in a single block (also known as uoffset or uncompressed_offset).

Methods

impl VirtualOffset

pub fn from_raw(raw: u64) -> VirtualOffset

Construct Virtual offset from raw value.

pub fn from(block_offset: u64, contents_offset: u16) -> Self

Construct Virtual offset from block_offset and contents_offset.

pub fn raw(&self) -> u64

Get the raw value.

pub fn block_offset(&self) -> u64

Get the block offset. Represents the offset in the Bgzip file to the beginning of the block.

pub fn contents_offset(&self) -> u16

Get the contents offset. Represents the offset into the uncompressed contents of the block.

pub fn equal(&self, block_offset: u64, contents_offset: u16) -> bool

Checks if the self is the same as block_offset << 16 | contents_offset.
