Cargo Features

snmptools has no features set by default.

[dependencies]
snmptools = { version = "0.0.11", features = ["dynamic", "static"] }
dynamic = libloading, once_cell
static = netsnmp-sys-nocrypto

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.
