Struct InstallResult 

pub struct InstallResult {
    pub config_path: PathBuf,
    pub ssh_public_key: String,
    pub overridden_global_signing_key: Option<String>,
    pub global_committer_email: Option<String>,
}

Output of install. Mostly informational — used for the post-install summary the caller prints.

Fields

config_path: PathBuf

Path the JSON config was written to.

ssh_public_key: String

SSH public key string (ssh-ed25519 …) for the user to paste into their git host’s signing-key settings.

overridden_global_signing_key: Option<String>

Set to the previous --global user.signingKey value if a non-global install just shadowed it. The caller can flag this to the operator so they aren’t surprised when inspecting git config --list.

global_committer_email: Option<String>

Set when a --global install just made a DID the committer email for every repository on the machine.

Correct for a contributor in one community, and wrong the moment there are two: the identity a commit claims has to match the key that signs it, so a single global value silently claims the wrong community everywhere else. The caller surfaces this with the per-community alternative rather than refusing — the single-community case is real and --global is the right tool for it.
