Struct Lens

pub struct Lens<'a>(/* private fields */);

Lens used for LensSelector. Internally mapped to a tuple of a slice of Token and Option of LensValue.

Implementations

impl<'a> Lens<'a>

pub fn new(tokens: &[Token<'a>], value: Option<LensValue<'a>>) -> Lens<'a>

Creates a new Lens.

pub fn get(&self) -> (Vec<Token<'a>>, Option<LensValue<'a>>)

Gets the content of a Lens.

Trait Implementations

impl<'a> Clone for Lens<'a>

fn clone(&self) -> Lens<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Lens<'a>

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

Formats the value using the given formatter.

impl Display for Lens<'_>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Lens<'a>

fn eq(&self, other: &Lens<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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