Struct LensPath 

pub struct LensPath {
    pub elements: Vec<LensPathElement>,
}

Describes a lens relative to a source data structure.

Fields

elements: Vec<LensPathElement>

The path elements.

Implementations

impl LensPath

pub fn empty() -> LensPath

Creates a new LensPath with no elements.

pub fn new(id: u64) -> LensPath

Creates a new LensPath with a single element.

pub fn from_index(index: usize) -> LensPath

Creates a new LensPath with a single index (for an indexed type such as Vec).

pub fn from_pair(id0: u64, id1: u64) -> LensPath

Creates a new LensPath with two elements.

pub fn from_vec(ids: Vec<u64>) -> LensPath

Creates a new LensPath from a vector of element identifiers.

pub fn concat(lhs: LensPath, rhs: LensPath) -> LensPath

Creates a new LensPath that is the concatenation of the two paths.

Trait Implementations

impl Clone for LensPath

fn clone(&self) -> LensPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LensPath

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

Formats the value using the given formatter.

impl Ord for LensPath

fn cmp(&self, other: &LensPath) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LensPath

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

impl PartialOrd for LensPath

fn partial_cmp(&self, other: &LensPath) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
