Module log 

Safe, ergonomic logging facilities for cFS.

System log and console

The [log!] and [printf!] macros write to the cFE System Log and the OSAL console, respectively.

Event Services (EVS)

The [info!], [warn!], and [err!] macros send EVS events with println!-like formatting. The event ID is derived from the source line number automatically.

info!("system nominal")?;
warn!("temperature high: {} C", temp)?;
err!("{} failed", subsystem)?;

Constants

EVS_MAX_MSG_SIZE

The maximum formatted EVS message size, from cFE mission config.

MAX_PRINTF_MSG_SIZE

The maximum size of a single OS_printf message, from OSAL configuration.

SYSLOG_MAX_MSG_SIZE

The maximum size of a single cFE System Log message, from cFE configuration.
