RestoredGuardianConfig

fedimint_server::config::setup

Struct RestoredGuardianConfig 

Source 
pub struct RestoredGuardianConfig {
    pub cfg: ServerConfig,
    restore_dir: PathBuf,
}
Expand description

Restored guardian configuration staged in a temporary directory.

Restore is intentionally split into two phases. First the uploaded backup is unpacked into restore_dir and parsed into cfg without touching the live config files. Later, after the caller performs cross-checks that need the full server context, RestoredGuardianConfig::install moves the staged files into the real data directory.

Fields§

§cfg: ServerConfig

Parsed server config read from the staged files.

§restore_dir: PathBuf

Temporary directory holding the exact files that will be installed.

Implementations§

Source§

impl RestoredGuardianConfig

Source

pub fn cleanup(&self)

Best-effort cleanup of the staged restore directory.

This is used on validation and handoff failures before the staged files become live config. Cleanup failures are only logged because callers are already handling another restore error.

Source

pub fn install(self, data_dir: &Path) -> Result<ServerConfig>

Install the staged restored config into data_dir.

This consumes self because after install there must be no separate staged restore state. The method refuses to overwrite existing live files, moves each expected file from restore_dir into data_dir, and tries to roll back already moved files if a later move fails. On success the temp directory is removed and the parsed ServerConfig is returned for consensus startup.
