Struct JsonExpr 

pub struct JsonExpr {
    pub op: JsonExprOp,
    pub formatted: Expr,
    pub path: Expr,
    pub passing: Vec<(String, Expr)>,
    pub returning: JsonReturning,
    pub on_empty: Option<JsonBehavior>,
    pub on_error: JsonBehavior,
    pub wrapper: JsonWrapper,
    pub omit_quotes: bool,
    pub json_coercion: bool,
    pub io_coercion: bool,
    pub column: Option<String>,
}

JsonExpr: JSON_EXISTS, JSON_QUERY or JSON_VALUE.

Fields

op: JsonExprOp

formatted: Expr

The context item as a jsonb value.

path: Expr

The path, of type jsonpath.

passing: Vec<(String, Expr)>

The names and the values of the PASSING clause.

returning: JsonReturning

on_empty: Option<JsonBehavior>

ON EMPTY, which JSON_EXISTS does not have.

on_error: JsonBehavior

wrapper: JsonWrapper

omit_quotes: bool

OMIT QUOTES, which is always true for JSON_VALUE.

json_coercion: bool

True when the executor casts the result to the type of RETURNING as json_populate_type does.

io_coercion: bool

True when the executor casts the text of the result to the type of RETURNING with its input function.

column: Option<String>

column_name: the name of the column of JSON_TABLE that the node computes, which the errors show.

Implementations

impl JsonExpr

pub fn children(&self) -> Vec<&Expr>

The context item, the path, the values of PASSING and the values of the behaviors.

pub fn children_mut(&mut self) -> Vec<&mut Expr>

JsonExpr::children, to change.
