fqcFASTQ compression in Rust

A block-indexed `.fqc` archive tool for compressing, restoring, inspecting, and verifying FASTQ data without turning project maintenance into a platform.

🧬

FASTQ-aware by design

Sequences, qualities, read IDs, and paired-end layout are encoded as separate archive concerns instead of being hidden inside a generic compressed stream.

📦

Block-indexed archives

The `.fqc` container keeps per-block metadata, a footer, and an index so `info`, `verify`, and range-oriented workflows have structure to work with.

🔍

Operational commands included

The same binary ships `compress`, `decompress`, `info`, and `verify`; users do not need sidecar scripts to validate an archive.

⚙️

Explicit memory modes

Default archive mode optimizes globally, `--streaming` favors strict memory control, and `--memory-limit 0` means automatic memory selection.

Pick the right path

Need	Command shape
Standard single-end archive	`fqc compress -i reads.fastq -o reads.fqc`
Low-memory compression	`fqc compress -i reads.fastq -o reads.fqc --streaming --memory-limit 1024`
Paired-end input	`fqc compress -i reads_R1.fastq -2 reads_R2.fastq -o paired.fqc`
Check an archive before use	`fqc verify -i reads.fqc`
Inspect codecs and blocks	`fqc info -i reads.fqc --detailed --show-codecs`
