Struct FastaIndexEntry 

pub struct FastaIndexEntry {
    pub name: Vec<u8>,
    pub len: u64,
    pub offset: u64,
    pub line_bases: u64,
    pub line_width: u64,
}

One .fai-style FASTA index entry.

offset, line_bases, and line_width follow the SAMtools .fai convention over the uncompressed FASTA byte stream. When built from BGZF input, virtual_offset stores the BGZF virtual offset for offset.

Fields

name: Vec<u8>

Reference name, using the first whitespace-delimited token after >.

len: u64

Number of bases in the reference sequence.

offset: u64

Uncompressed byte offset of the first sequence byte.

line_bases: u64

Number of bases per full sequence line.

line_width: u64

Number of bytes per full sequence line, including line ending bytes.

Implementations

impl FastaIndexEntry

pub fn sequence_offset(&self, pos: u64) -> Result<u64>

Return the uncompressed FASTA byte offset for a zero-based sequence position.

Coordinates are 0-based and do not include FASTA line separators.

pub fn sequence_spans(&self, range: Range<u64>) -> Result<Vec<Range<u64>>>

Return physical FASTA byte spans covering a zero-based half-open sequence range.

Each returned span points only at sequence bytes and excludes physical newline bytes.

Trait Implementations

impl Clone for FastaIndexEntry

fn clone(&self) -> FastaIndexEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FastaIndexEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for FastaIndexEntry

impl PartialEq for FastaIndexEntry

fn eq(&self, other: &FastaIndexEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
