Enum Token 

pub enum Token {
    Positional(String),
    LongFlag {
        name: String,
        value: Option<String>,
    },
    ShortFlag {
        name: char,
        value: Option<String>,
    },
    ShortCluster(Vec<char>),
    EndOfOptions,
}

Pure lexer that tokenizes raw CLI arguments into typed tokens.

No schema knowledge – just lexical classification. The tokenizer distinguishes positionals, long flags, short flags, short clusters, and the end-of-options separator (--).

Variants

Positional(String)

Bare positional value (no leading dash)

LongFlag

Long flag: –flag (no value) or –flag=value

Fields

name: String

value: Option<String>

ShortFlag

Short flag: -f (no value) or -f=value

Fields

name: char

value: Option<String>

ShortCluster(Vec<char>)

Short cluster: -abc (multiple short flags combined)

EndOfOptions

End-of-options separator: –

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Token

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

Formats the value using the given formatter.

impl PartialEq for Token

fn eq(&self, other: &Token) -> 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.
