Cargo Features

[dependencies]
firefly-rust = { version = "0.6.0", default-features = false, features = ["std", "alloc", "panic_info", "sudo", "nalgebra_support"] }

default = alloc, nalgebra_support, panic_info, sudo

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

std

If disabled, the crate uses no_std.

alloc default

Enable support for allocating functions, like load_file_buf.
Requires a global allocator to be configured.

Affects fs::FileBuf, fs::load_file_buf, canvas::CanvasBuf, sudo::DirBuf, sudo::load_file_buf…

panic_info default

If app panics, show panic info (message, file name, line number).
Increases the binary size.

sudo default

Enable support for functions requiring sudo.

Affects firefly-rust::sudo…

nalgebra_support default = nalgebra

Enable support for casting graphic primitives to and from nalgebra crate primitives.

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.
