Struct ParsedArg

pub struct ParsedArg<'s> { /* private fields */ }

Command-line Argument

Implementations

impl<'s> ParsedArg<'s>

pub fn is_empty(&self) -> bool

Argument is length of 0

pub fn is_stdio(&self) -> bool

Does the argument look like a stdio argument (-)

pub fn is_escape(&self) -> bool

Does the argument look like an argument escape (--)

pub fn is_negative_number(&self) -> bool

Does the argument look like a negative number?

This won’t parse the number in full but attempts to see if this looks like something along the lines of -3, -0.3, or -33.03

pub fn to_long(&self) -> Option<(Result<&str, &OsStr>, Option<&OsStr>)>

Treat as a long-flag

pub fn is_long(&self) -> bool

Can treat as a long-flag

pub fn to_short(&self) -> Option<ShortFlags<'_>>

Treat as a short-flag

pub fn is_short(&self) -> bool

Can treat as a short-flag

pub fn to_value_os(&self) -> &OsStr

Treat as a value

NOTE: May return a flag or an escape.

pub fn to_value(&self) -> Result<&str, &OsStr>

Treat as a value

NOTE: May return a flag or an escape.

pub fn display(&self) -> impl Display + '_

Safely print an argument that may contain non-UTF8 content

This may perform lossy conversion, depending on the platform. If you would like an implementation which escapes the path please use Debug instead.

Trait Implementations

impl<'s> Clone for ParsedArg<'s>

fn clone(&self) -> ParsedArg<'s>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'s> Debug for ParsedArg<'s>

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

Formats the value using the given formatter.

impl<'s> Hash for ParsedArg<'s>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'s> Ord for ParsedArg<'s>

fn cmp(&self, other: &ParsedArg<'s>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'s> PartialEq for ParsedArg<'s>

fn eq(&self, other: &ParsedArg<'s>) -> 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.

impl<'s> PartialOrd for ParsedArg<'s>

fn partial_cmp(&self, other: &ParsedArg<'s>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
