Implementations

impl OutputSpec

pub fn inherit() -> Self

For stdout, use the same file for stdin. For stderr, use the same file for stdout.

pub fn null() -> Self

Connect /dev/null to the output.

pub fn journal() -> Self

Log the output into system journal.

pub fn file<T: AsRef<str>>(path: T) -> Self

Specify a path where the file will be overwritten from offset 0. If the file does not exist, it will be created.

This setting will be unavailable if the feature systemd_236 is disabled.

pub fn truncate<T: AsRef<str>>(path: T) -> Self

Like OutputSpec::file, but the file will be truncated before written.

This setting will be unavailable if the feature systemd_248 is disabled.

pub fn append<T: AsRef<str>>(path: T) -> Self

Like OutputSpec::file, but the file will be written from its end, instead of offset 0.

This setting will be unavailable if the feature systemd_240 is disabled.
