Struct JsonPath 

pub struct JsonPath(/* private fields */);

Type-safe JSON Path for addressing nodes in JSON structures

This is a pure domain object. Serialization should be handled in the application layer via DTOs, but serde is temporarily kept for compatibility with existing code.

TODO: Remove Serialize, Deserialize derives once all serialization uses DTOs

Implementations

impl JsonPath

pub fn new(path: impl Into<String>) -> Result<JsonPath, DomainError>

Create new JSON path with validation

pub fn root() -> JsonPath

Create root path

pub fn append_key(&self, key: &str) -> Result<JsonPath, DomainError>

Append a key to the path

pub fn append_index(&self, index: usize) -> JsonPath

Append an array index to the path

pub fn as_str(&self) -> &str

Get the path as a string

pub fn parent(&self) -> Option<JsonPath>

Get the parent path (if any)

pub fn last_segment(&self) -> Option<PathSegment>

Get the last segment of the path

pub fn depth(&self) -> usize

Get the depth of the path (number of segments)

pub fn is_prefix_of(&self, other: &JsonPath) -> bool

Check if this path is a prefix of another path

Trait Implementations

impl Clone for JsonPath

fn clone(&self) -> JsonPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonPath

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonPath

fn deserialize<__D>( __deserializer: __D, ) -> Result<JsonPath, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for JsonPath

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

Formats the value using the given formatter.

impl From<JsonPath> for JsonPathDto

fn from(json_path: JsonPath) -> Self

Converts to this type from the input type.

impl FromDto<JsonPathDto> for JsonPath

Utility trait implementation for JsonPath

type Error = DomainError

fn from_dto(dto: JsonPathDto) -> Result<Self, Self::Error>

impl Hash for JsonPath

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 JsonPath

fn eq(&self, other: &JsonPath) -> 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 Serialize for JsonPath

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToDto<JsonPathDto> for JsonPath

Utility trait implementation for JsonPath

fn to_dto(self) -> JsonPathDto

impl TryFrom<JsonPathDto> for JsonPath

type Error = DomainError

The type returned in the event of a conversion error.

fn try_from(dto: JsonPathDto) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for JsonPath

impl StructuralPartialEq for JsonPath
