Function parse_remote_manifest

atomic-cli/src/commands/push/helpers.rs:338–348

Parse and verify a remote manifest, mapping failures to remote errors. The declared state must equal the fold of the log — a remote that sends an inconsistent manifest is broken, and we refuse to plan against it.

(view: &str, text: &str, url: &str)
