[features]
default = ["std", "opus", "g729"]
# `std` enables the allocating convenience API (`encode`/`decode` returning
# `Vec`, `create_encoder`/`create_decoder` returning `Box`, ...). Without it
# the crate is `#![no_std]`; Opus then needs an `alloc` (its ~250 KB
# encoder/decoder working set is boxed), the other codecs are heap-free.
#
# `std` also enables opus-rs's `heap` feature (requires std there): the
# encoder/decoder codec states are constructed INSIDE a Box instead of on
# the caller's stack. OpusEncoder's inline state is ~250 KB without it, so
# `OpusEncoder::new` alone could consume most of an 8 MB thread stack —
# fatal for deep async call chains in debug builds.
#
# `std` also enables fearless_simd's runtime CPU feature detection, so the
# resamplers pick the best SIMD level available. Without it the SIMD level is
# fixed at compile time (SSE2 on x86_64 unless `-C target-feature` says more).
std = ["g729-sys?/std", "opus-rs?/std", "opus-rs?/heap", "fearless_simd/std"]
# Opus support. On by default. opus-rs uses `libm` for transcendentals when
# `std` is off (no_std build).
opus = ["dep:opus-rs", "opus-rs/libm"]
# G.729 support. On by default. `g729-sys` is pure Rust and works without
# `std`; disabling this feature drops the codec entirely (smaller build).
