Struct rsonpath::query::JsonString

pub struct JsonString { /* private fields */ }

String to search for in a JSON document, conforming to the RFC7159, section 7

Represents the bytes defining a label/key in a JSON object that can be matched against when executing a query.

Examples

let needle = JsonString::new("needle");

assert_eq!(needle.bytes(), "needle".as_bytes());
assert_eq!(needle.bytes_with_quotes(), "\"needle\"".as_bytes());

Implementations

impl JsonString

pub fn new(string: &str) -> Self

Create a new label from UTF8 input.

pub fn bytes(&self) -> &[u8]

Return the raw bytes of the string, guaranteed to be block-aligned.

pub fn bytes_with_quotes(&self) -> &[u8]

Return the bytes representing the string with a leading and trailing double quote symbol ", guaranteed to be block-aligned.

pub fn display(&self) -> impl Display + '_

Return a display object with a UTF8 representation of this string.

If the string contains invalid UTF8, the value will always be "[invalid utf8]".

Trait Implementations

impl<'a> Arbitrary<'a> for JsonString

Available on crate feature arbitrary only.

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

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

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

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 JsonString

fn clone(&self) -> JsonString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JsonString

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

Formats the value using the given formatter.

impl Display for JsonString

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

Formats the value using the given formatter.

impl<'q> From<&'q JsonString> for TransitionLabel<'q>

fn from(member_name: &'q JsonString) -> Self

Converts to this type from the input type.

impl Hash for JsonString

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<&[u8]> for JsonString

fn eq(&self, other: &&[u8]) -> 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.

impl PartialEq<[u8]> for JsonString

fn eq(&self, other: &[u8]) -> 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.

impl PartialEq<JsonString> for &[u8]

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

impl PartialEq<JsonString> for [u8]

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

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

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