Implementations

impl SysusersEntry

pub(crate) fn next_token(s: &str) -> Option<(&str, &str)>

Given an input string, finds the next “token” which is normally delimited by whitespace, but “quoted strings” are also supported. Returns that token and the remainder. If there are no more tokens, this returns None.

Yes this is a lot of manual parsing and there’s a ton of crates we could use, like winnow, but this problem domain is just simple enough that I decided not to learn that yet.

pub(crate) fn next_token_owned(s: &str) -> Option<(String, &str)>

pub(crate) fn next_optional_token(s: &str) -> Option<(Option<&str>, &str)>

pub(crate) fn next_optional_token_owned( s: &str, ) -> Option<(Option<String>, &str)>

pub(crate) fn parse(s: &str) -> Result<Option<SysusersEntry>>

Trait Implementations

impl Debug for SysusersEntry

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

Formats the value using the given formatter.

impl PartialEq for SysusersEntry

fn eq(&self, other: &SysusersEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
