Struct LdkTracingLogger 

struct LdkTracingLogger {
    in_test_env: bool,
}

Forwards ldk-node’s log records into the gateway’s tracing subscriber.

By default ldk-node writes to its own append-only ldk_node/ldk_node.log file, which is invisible to stdout/stderr log collectors and grows without bound. Routing the records through tracing (under the LOG_LIGHTNING_LDK target) puts them alongside the rest of gatewayd’s logs and makes them filterable via RUST_LOG.

Fields

in_test_env: bool

Whether we’re running under devimint/tests. When set, some benign LDK error logs that are expected in regtest are downgraded to avoid spamming the test output. See Self::downgraded_level.

Implementations

impl LdkTracingLogger

fn downgraded_level(&self, record: &LogRecord<'_>) -> LogLevel

Returns the level to emit record at, downgrading benign-but-noisy LDK errors when running under devimint/tests.

In regtest there is no fee-rate history, so ldk-node logs “Failed to retrieve fee rate estimates … Falling back to default” at Error on essentially every sync. This is harmless (LDK falls back to a default feerate), so in test environments we emit it at Debug instead. In production the original Error level is preserved, since a persistent failure there can indicate a real problem.

Trait Implementations

impl LogWriter for LdkTracingLogger

fn log(&self, record: LogRecord<'_>)

Log the record.
