Struct Stop 

pub struct Stop;

A special option value, can stop the policy, using for implement --.

Example

use aopt::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {

    let mut parser = AFwdParser::default();

    parser.add_opt("stop".infer::<aopt::value::Stop>())?;

    // -w will processed, it is set before `--`
    parser.add_opt("-w=i")?;

    // -o will not processed, it is set after `--`
    parser.add_opt("-o=s")?;

    // fo will processed, it is not an option
    parser.add_opt("foo=p@1")?;

    parser.parse(Args::from(["app", "-w=42", "--", "-o", "val", "foo"]))?;

    assert_eq!(parser.find_val::<i64>("-w")?, &42);
    assert!(parser.find_val::<String>("-o").is_err());
    assert_eq!(parser.find_val::<bool>("foo")?, &true);
    Ok(())
}

12.2 Utility Syntax Guidelines

Guideline 10:

The first -- argument that is not an option-argument should be accepted as a delimiter indicating the end of options.
Any following arguments should be treated as operands, even if they begin with the '-' character.

Trait Implementations

where Self: Sized + 'static, Self::Val: RawValParser, C: ConfigValue + Default,

For type Stop, swap the name and default alias(--) when build configuration.

type Val = Stop

impl Ord for Stop

fn cmp(&self, other: &Stop) -> 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 PartialEq for Stop

fn eq(&self, other: &Stop) -> 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 PartialOrd for Stop

fn partial_cmp(&self, other: &Stop) -> 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.

impl RawValParser for Stop

type Error = Error

impl Serialize for Stop

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
