Struct postgres_parser::sys::ArrayExpr

#[repr(C)]pub struct ArrayExpr {
    pub xpr: Expr,
    pub array_typeid: Oid,
    pub array_collid: Oid,
    pub element_typeid: Oid,
    pub elements: *mut List,
    pub multidims: bool,
    pub location: c_int,
}

ArrayExpr an ARRAY[] expression

Note: if multidims is false, the constituent expressions all yield the scalar type identified by element_typeid. If multidims is true, the constituent expressions all yield arrays of element_typeid (ie, the same type as array_typeid); at runtime we must check for compatible subscripts.

Fields

xpr: Expr

array_typeid: Oid

array_collid: Oid

type of expression result

element_typeid: Oid

OID of collation, or InvalidOid if none

elements: *mut List

common type of array elements

multidims: bool

the array elements or subarrays

location: c_int

true if elements are subarrays
