Struct ParsedArgs 

pub struct ParsedArgs {
    pub flags: HashSet<String>,
    pub options: HashMap<String, String>,
    pub positional: Vec<String>,
}

Represents a set of parsed arguments.

You get this struct back after a successful call to Parser::parse().

Fields

flags: HashSet<String>

A set of all flags that were present.

options: HashMap<String, String>

A map of all options and their string values.

positional: Vec<String>

A vector of all positional arguments in the order they appeared.

Implementations

impl ParsedArgs

pub fn get_value_as<T: FromStr>(&self, name: &str) -> Option<Result<T, T::Err>>

Gets and parses the value of an option into a specific type.

This method attempts to find an option by its name and then parse its string value into any type T that implements FromStr.

Returns

• None: If the option was not provided by the user.
• Some(Ok(value)): If the option was found and successfully parsed.
• Some(Err(error)): If the option was found but parsing failed.

Examples

// Assuming `results` is a ParsedArgs
// let port = results.get_value_as::<u32>("port");
