Struct TwinConfig 

pub struct TwinConfig {
    pub primary: String,
    pub joined_at_unix_ms: i64,
}

What twin.json says.

Fields

primary: String

The primary’s control plane, host:port.

joined_at_unix_ms: i64

When this box became a twin.

Implementations

impl TwinConfig

pub fn load(root: &Path) -> Result<Option<Self>>

Ok(None) = not a twin. A twin.json that does not parse is an error, never “not a twin”: a twin that booted as a primary would frame its own KEK and fork the numbers.

pub fn save(&self, root: &Path) -> Result<()>

Write it (unframed, atomic).
