Struct dpiJsonObject 

#[repr(C)]
pub struct dpiJsonObject {
    pub numFields: u32,
    pub fieldNames: *mut *mut c_char,
    pub fieldNameLengths: *mut u32,
    pub fields: *mut dpiJsonNode,
    pub fieldValues: *mut dpiDataBuffer,
}

This structure is used for passing JSON objects to and from the database.

Fields

numFields: u32

Specifies the number of fields that are found in the JSON object. This also identifies the number of elements in each of the remaining arrays.

fieldNames: *mut *mut c_char

Specifies an array of field names that are found in the JSON object. Each element is a byte string encoded in UTF-8. The length of each byte string is found in the [dpiJsonObject.fieldNameLengths] member.

fieldNameLengths: *mut u32

Specifies an array of lengths for the names of the fields found in the JSON object.

fields: *mut dpiJsonNode

Specifies an array of JSON nodes that are the values of the fields found in the JSON object. Each of these is a structure of type dpiJsonNode.

fieldValues: *mut dpiDataBuffer

Specifies an array of buffers that contain the data for the values of the fields found in the JSON object. This member should not be used directly. Instead, the [dpiJsonNode.value] member of the corresponding node in the member [dpiJsonObject.fields] should be used.
