comparison libpam-sys/src/constants.rs @ 109:bb465393621f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Minor cleanup and reorg. - Use those nice new macros we just implemented. - Straighten out the macro file. - Move the `BinaryPayload` into `structs.rs`, leaving helpers behind.
