Struct TokenComponent 

pub struct TokenComponent {
    pub signum: i8,
    pub digits: String,
}

One element of a comma-separated token list.

Examples

use dynomite::conf::TokenComponent;
let pos = TokenComponent::parse("42").unwrap();
assert_eq!(pos.signum, 1);
assert_eq!(pos.digits, "42");
let zero = TokenComponent::parse("0").unwrap();
assert_eq!(zero.signum, 0);

Fields

signum: i8

-1 for negative, 0 for zero, 1 for positive.

digits: String

Decimal digits without the optional leading sign.

Implementations

impl TokenComponent

pub fn parse(raw: &str) -> Result<Self, ConfError>

Parse a single component (no commas, no surrounding whitespace).

Examples

use dynomite::conf::TokenComponent;
let neg = TokenComponent::parse("-7").unwrap();
assert_eq!(neg.signum, -1);
assert_eq!(neg.digits, "7");
assert!(TokenComponent::parse("").is_err());
assert!(TokenComponent::parse("-").is_err());
assert!(TokenComponent::parse("12a").is_err());

Trait Implementations

impl Clone for TokenComponent

fn clone(&self) -> TokenComponent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenComponent

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

Formats the value using the given formatter.

impl Display for TokenComponent

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

Formats the value using the given formatter.

impl Hash for TokenComponent

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 PartialEq for TokenComponent

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