Struct ql2::Datum [−][src]
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
[src]
pub fn type(&self) -> DatumType
[src]
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)
[src]
Sets type
to the provided enum value.
pub fn r_bool(&self) -> bool
[src]
Returns the value of r_bool
, or the default value if r_bool
is unset.
pub fn r_num(&self) -> f64
[src]
Returns the value of r_num
, or the default value if r_num
is unset.
pub fn r_str(&self) -> &str
[src]
Returns the value of r_str
, or the default value if r_str
is unset.
