Implementations

impl Settings

pub fn from_obsolete_args(args: &ObsoleteArgs, name: Option<&OsString>) -> Self

pub fn from(matches: &ArgMatches) -> UResult<Self>

pub fn has_only_stdin(&self) -> bool

pub fn has_stdin(&self) -> bool

pub fn num_inputs(&self) -> usize

pub fn check_warnings(&self)

Check Settings for problematic configurations of tail originating from user provided command line arguments and print appropriate warnings.

pub fn verify(&self) -> VerificationResult

Verify Settings and try to find unsolvable misconfigurations of tail originating from user provided command line arguments. In contrast to Settings::check_warnings these misconfigurations usually lead to the immediate exit or abortion of the running tail process.

Trait Implementations

impl Debug for Settings

fn fmt(&self, f: &mut Formatter<'_>) -> Result
