Cargo Features

[dependencies]
literalext = { version = "0.2.0", default-features = false, features = ["i128", "proc-macro", "dummy", "proc-macro2"] }
default = proc-macro2

The proc-macro2 feature is set by default whenever literalext is added without default-features = false somewhere in the dependency tree.

i128
proc-macro
dummy

Affects literalext::DummyLiteral

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](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).

proc-macro2 is implicit

proc-macro2 default

Enables proc-macro2 ^0.2
