Function resolve_filter 

Source 
pub fn resolve_filter(
    persisted: Option<&str>,
    dig_log: Option<&str>,
    rust_log: Option<&str>,
) -> String
Expand description

Resolve the effective filter directive by precedence (SPEC §5): the first non-empty of persisted > dig_log > rust_log, else DEFAULT_DIRECTIVE. Whitespace-only inputs count as empty (an exported-but-blank env var must not silence logging).
