# We use `Arcow` to reduce the memory overhead of having multiple "copies" of a
# Soundtrack around, without harming ergonomics.
arcow = "1.1.1"
# Saves us a lot of memory and heap churn, in the exceptionally common case
# where flow/node/sequence/sound names are short.
compact_str = "0.7.1"
# We love their locks and channels.
crossbeam = "0.8"
# We use `#[derivative(Debug)]` to aid in deriving `Debug` for some types.
derivative = "2.2"
# We use futures to schedule loading, even if we're doing foreground loading.
# (We have our own thin built-in runtime for the foreground case.)
futures = "0.3.29"
# We use this library to resample sounds if needed.
libsoxr = "0.2.9"
# If the "switchyard" feature is enabled, we use this crate to decide how many
# threads we should spawn for background loading (if the caller didn't request
# a specific number).

# We use `once_cell::sync::Lazy` in a few places in our timebase parsing.

# "Shellish" is the fundamental syntax of the Second Music System Soundtrack
# Language.

# schedule threads for background loading and (some day) decoding.

# If the "tokio" feature is enabled, we provide an implementation of our
# `Runtime` trait that interfaces with Tokio runtimes. (There should be nothing
# stopping you from making such an implementation yourself. This is just more
# convenient.)

# Exposes an implementation of TaskRuntime for Switchyard, and the convenient
# Engine::new() function that uses Switchyard behind the scenes. Use this
# unless you KNOW you don't want it.

# Exposes an implementation of TaskRuntime for Tokio. Use this if you have a
# Tokio runtime in your game already, and you want SMS to make use of it.

# Exposes the EngineCommandIssuer trait. You should only use/need this if you
# are creating an FFI binding.
