Struct rsonpath_syntax::Slice

pub struct Slice { /* private fields */ }

Slice selector defining the start and end bounds, as well as the step value and direction.

The start index is inclusive defaults to Index::FromStart(0).

The end index is exclusive and optional. If None, the end of the slice depends on the step direction:

• if going forward, the end is len of the array;
• if going backward, the end is 0.

The step defaults to Step::Forward(1). Note that Step::Forward(0) is a valid value and is specified to result in an empty slice, regardless of start and end.

Examples

let slice = Slice::default();
assert_eq!(slice.start(), Index::FromStart(JsonUInt::ZERO));
assert_eq!(slice.end(), None);
assert_eq!(slice.step(), Step::Forward(JsonUInt::ONE));

Implementations

impl Slice

pub fn new(start: Index, end: Option<Index>, step: Step) -> Self

Create a new Slice from given bounds and step.

pub fn start(&self) -> Index

Get the start index of the Slice.

pub fn end(&self) -> Option<Index>

Get the end index of the Slice.

pub fn step(&self) -> Step

Get the step of the Slice.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Slice

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for Slice

fn clone(&self) -> Slice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Slice

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

Formats the value using the given formatter.

impl Default for Slice

fn default() -> Self

Returns the “default value” for a type.

impl Display for Slice

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

Formats the value using the given formatter.

impl From<SliceBuilder> for Slice

fn from(value: SliceBuilder) -> Self

Converts to this type from the input type.

impl Hash for Slice

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 Slice

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

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

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.
