[dependencies]
memvid-core = { version = "2.0.139", default-features = false, features = ["lex", "extractous", "pdf_extract", "pdf_oxide", "vec", "clip", "mmap", "pdfium", "temporal_track", "temporal_enrich", "parallel_segments", "logic_mesh", "whisper", "metal", "cuda", "accelerate", "replay", "encryption", "symspell_cleanup", "api_embed", "simd", "hnsw_bench", "jsonwebtoken", "rustfft"] }

default = lex, pdf_extract, simd

These default features are set whenever memvid-core is added without default-features = false somewhere in the dependency tree.

lex default

pdf_oxide disabled - cff-parser panics on ligature fonts (uniFB01/uniFB02) symspell_cleanup - enables robust PDF text repair (requires make download-models for dictionaries)

Enables tantivy ^0.25.0

extractous

Enables extractous

extractous uses GraalVM native compilation which doesn't work on Windows ARM or WSL2 on ARM Enable with --features extractous for full document extraction (PDF, DOCX, etc.)

Affects extract::DocumentProcessor…

pdf_extract default

Pure Rust PDF extraction - faster than lopdf for text extraction, cross-platform

Enables pdf-extract

Pure Rust PDF text extraction - used as primary extractor when extractous is disabled

pdf_oxide

High-accuracy PDF extraction with perfect word spacing (recommended for 2025+)

Enables pdf_oxide

High-accuracy PDF text extraction with perfect word spacing (2025)
