[features]
default = ["std", "opus"]
# `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 = ["g729-sys/std", "opus-rs?/std", "opus-rs?/heap"]
# Opus support. On by default. opus-rs uses `libm` for transcendentals when
# `std` is off (no_std build).
