Struct RollbackContext 

pub struct RollbackContext<'a> {
    pub env: &'a str,
    pub repo: &'a Path,
    pub target_file: &'a str,
    pub target: &'a Target,
    pub reader: &'a dyn TreeReader,
    pub host: &'a dyn ApplyHost,

}

What a rollback drives. The target file names the gateway, the mode and the master node; nothing else of the declared repo is read.

Fields

env: &'a str

The --env value.

repo: &'a Path

The repo root (the run directories live below it).

target_file: &'a str

Repo-relative path of the target file (targets/<env>.yaml).

target: &'a Target

The parsed target.

reader: &'a dyn TreeReader

The read half of the master’s host.

host: &'a dyn ApplyHost

The write seam of the master’s host.

deploy: &'a dyn DeployApi

The gateway REST surface (lock, scan, mode, restart list).

gateway: &'a dyn GatewayApi

The gateway surface the preflights read (identity, Designers).

backup: Option<&'a BackupNode<'a>>

The backup node (a read-only handle), when the target has one.

clock: &'a dyn Clock

The monotonic clock the lock is judged by.

observer: &'a dyn ApplyObserver

Hears each step.
