Struct JsonPath 

pub struct JsonPath {
    pub column: String,
    pub segments: Vec<PathSegment>,
    pub as_text: bool,
}

A JSON path expression for navigating JSON documents.

Fields

column: String

The column name containing JSON.

segments: Vec<PathSegment>

Path segments (field names or array indices).

as_text: bool

Whether to return text (::text in PostgreSQL).

Implementations

impl JsonPath

pub fn new(column: impl Into<String>) -> Self

Create a new JSON path starting from a column.

pub fn from_path(column: impl Into<String>, path: &str) -> Self

Create a path from a JSONPath string (e.g., “$.user.name”).

pub fn field(self, name: impl Into<String>) -> Self

Add a field access segment.

pub fn index(self, idx: i64) -> Self

Add an array index segment.

pub fn all(self) -> Self

Add an array wildcard segment.

pub fn text(self) -> Self

Return the value as text instead of JSON.

pub fn to_postgres_expr(&self) -> String

Convert to PostgreSQL JSON path expression.

pub fn to_mysql_expr(&self) -> String

Convert to MySQL JSON path expression.

pub fn to_sqlite_expr(&self) -> String

Convert to SQLite JSON path expression.

pub fn to_mssql_expr(&self) -> String

Convert to MSSQL JSON path expression.

pub fn to_jsonpath_string(&self) -> String

Convert to standard JSONPath string.

pub fn to_mongodb_path(&self) -> String

Convert to MongoDB dot notation.

pub fn to_sql(&self, db_type: DatabaseType) -> String

Convert to SQL expression for the specified database.

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

Formats the value using the given formatter.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a JsonPath> for JsonPathRef<'a>

fn from(path: &'a JsonPath) -> Self

Converts to this type from the input type.

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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
