Cargo Features

[dependencies]
crc-any = { version = "2.5.0", default-features = false, features = ["std", "alloc", "development", "heapless"] }
default = alloc

The alloc feature is set by default whenever crc-any is added without default-features = false somewhere in the dependency tree.

std development?
alloc default = debug-helper
development = std

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.

Enables heapless

heapless:

static friendly data structures that don't require dynamic memory allocation
