Struct spdlog::LogCrateProxy

pub struct LogCrateProxy { /* private fields */ }

Available on crate feature log only.

Log crate proxy.

It forwards all log messages from log crate to default_logger by default, and you can set a separate logger for it via LogCrateProxy::set_logger.

If upstream dependencies use log crate to output log messages, they may also be received by LogCrateProxy.

Note that the log crate uses a different log level filter and by default it rejects all log messages. To make LogCrateProxy able to receive log messages from log crate, you may need to call log_crate::set_max_level with log_crate::LevelFilter.

Examples

use spdlog::log_crate as log;

spdlog::init_log_crate_proxy()?;
// Enable all log messages from `log` crate.
log::set_max_level(log::LevelFilter::Trace);

For more and detailed examples, see ./examples directory.

Implementations

pub fn set_logger(&self, logger: Option<Arc<Logger>>)

Sets a logger.

If the argument logger is None, the return value of default_logger will be used.
