Cargo Features

[dependencies]
jpeg-decoder = { version = "0.3.1", default-features = false, features = ["platform_independent", "nightly_aarch64_neon", "rayon"] }
default = rayon

The rayon feature is set by default whenever jpeg-decoder is added without default-features = false somewhere in the dependency tree.

platform_independent
nightly_aarch64_neon

Opt-in, this depends on Rust nightly. Will be changed to a no-op feature when the Rust feature is stabilized which is expected to be 1.61.

Affects neon::dequantize_and_idct_block_8x8, neon::color_convert_line_ycbcr

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
