Enum FacadeVariant

pub enum FacadeVariant {
    None,
    StdOut,
    StdErr,
    Syslog(String),
    File(PathBuf, bool),
}

Declaration of the different available log facacdes (log targets).

Errors

When parsing a FacadeVariant from a string, the following errors can occur:

• If the string does not match any of the known variants, a String is returned with an error message.
• If the string matches a known variant but the variant is not implemented, a String is returned with an error message.

Panics

There are some known panics that can occur when initializing or logging to a facade.

Panic on initialization

The Syslog variant will panic if the given facility is not a valid syslog facility.

The File variant will panic if the given filename is not a valid path or opening the file fails.

Panic on logging

Variants

None

Logging is disabled

StdOut

Log to stdout

Note: This bypasses the OutputCapture of std::io::stdout

StdErr

Log to stderr

Note: This bypasses the OutputCapture of std::io::stderr

Syslog(String)

Log to syslog

The first argument is the syslog facility (e.g. “user”)

File(PathBuf, bool)

Log to a file

The first argument is the filename The second argument is a boolean that indicates whether the file should be truncated
