Struct LoggingConfig 

pub struct LoggingConfig {
    pub level: String,
    pub file: Option<String>,
}

Logging configuration.

[logging]
level = "info"                          # default tracing filter
file = "/var/log/ndn/router.log"        # optional log file

Precedence (highest to lowest):

1. RUST_LOG environment variable
2. --log-level CLI flag
3. level field in this section

When file is set, logs are written to both stderr and the file so interactive use always shows output while the file captures a persistent record.

Fields

level: String

Default tracing filter string (e.g. "info", "ndn_engine=debug,warn").

Overridden by --log-level CLI flag or RUST_LOG env var.

file: Option<String>

Optional file path for persistent log output.

Parent directories are created automatically. When set, logs are written to both stderr and this file.
