Detailed Description

Abstract interface for logging strings.

Each log message has a type. Logging can be enabled or disabled for each type.

The actual string to log gets assembled from the format string and its arguments only if the type is supposed to be logged.

Examples

aio.cpp, https.cpp, and raw_https.cpp.

Member Function Documentation

log()

void log ( logmsg::type  t, String &&  fmt, Args &&...  args  )

inline

The

• fmt argument is a format string suitable for fz::sprintf

Assumes that all narrow string arguments are in the locale's current encoding.

Examples

aio.cpp, and https.cpp.

log_u()

void log_u ( logmsg::type  t, String &&  fmt, Args const &...  args  )

inline

The

• fmt argument is a format string suitable for fz::sprintf

Assumes that all narrow string arguments, excluding the format string, are in UTF-8
