Struct ql2::Datum

pub struct Datum {
    pub type: Option<i32>,
    pub r_bool: Option<bool>,
    pub r_num: Option<f64>,
    pub r_str: Option<String>,
    pub r_array: Vec<Datum>,
    pub r_object: Vec<AssocPair>,
}

A [Datum] is a chunk of data that can be serialized to disk or returned to the user in a Response. Currently we only support JSON types, but we may support other types in the future (e.g., a date type or an integer type).

Fields

type: Option<i32>

r_bool: Option<bool>

r_num: Option<f64>

r_str: Option<String>

r_array: Vec<Datum>

r_object: Vec<AssocPair>

Implementations

impl Datum

pub fn type(&self) -> DatumType

Returns the enum value of type, or the default if the field is unset or set to an invalid enum value.

pub fn set_type(&mut self, value: DatumType)

Sets type to the provided enum value.

pub fn r_bool(&self) -> bool

Returns the value of r_bool, or the default value if r_bool is unset.

pub fn r_num(&self) -> f64

Returns the value of r_num, or the default value if r_num is unset.

pub fn r_str(&self) -> &str

Returns the value of r_str, or the default value if r_str is unset.

Trait Implementations

impl Clone for Datum

fn clone(&self) -> Datum

Returns a copy of the value.

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

impl Message for Datum

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)
