proc-macro2A substitute implementation of the compiler's `proc_macro` API to decouple token-based libraries from the procedural macro use case.1.7Bdownloads/mo
base64encodes and decodes base64 as bytes or utf81.7Bdownloads/mo
cfg-ifA macro to ergonomically define an item depending on a large number of #[cfg]
parameters. Structured like an if-else chain, the first matching branch is the
item that gets emitted.1.5Bdownloads/mo
