Struct FastaConfig 

pub struct FastaConfig {
    pub batch_records: usize,
    pub buffer_size: usize,
    pub expected_seq_len: usize,
}

Configuration for FASTA readers.

Fields

batch_records: usize

Maximum number of records returned per batch.

Values below 1 are raised to 1. Larger batches reduce caller overhead but keep more sequence bytes resident until the next batch.

buffer_size: usize

Input buffer size used by streaming readers.

Values below 1024 are raised to 1024. Larger buffers can reduce I/O calls for compressed or high-latency streams; smaller buffers may improve cache behavior on simple in-memory inputs.

expected_seq_len: usize

Expected sequence length used as a preallocation hint.

This is only a hint for reusable scratch buffers. It does not reject longer records.

Implementations

impl FastaConfig

pub fn reference() -> Self

Return parser settings tuned for chromosome-scale reference FASTA records.

pub fn two_line(self) -> Self

Return a copy configured for strict two-line FASTA-oriented streaming.

Trait Implementations

impl Clone for FastaConfig

fn clone(&self) -> FastaConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FastaConfig

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

Formats the value using the given formatter.

impl Default for FastaConfig

fn default() -> Self

Returns the “default value” for a type.
