Implementations

impl Item

pub fn new(s: &str) -> Result<Self, PatternError>

Parses given string slice and constructs an Item (if possible)

Trait Implementations

impl Clone for Item

fn clone(&self) -> Item

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Item

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

Formats the value using the given formatter.

impl PartialEq<Item> for Item

fn eq(&self, other: &Item) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Item

impl Eq for Item

impl StructuralEq for Item

impl StructuralPartialEq for Item
