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.

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

Performs copy-assignment from source.

impl Debug for Datum

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Datum

fn default() -> Self

Returns the “default value” for a type.

impl Message for Datum

    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,

) -> Result<(), DecodeError> where
    B: Buf, 

fn encoded_len(&self) -> usize

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

fn clear(&mut self)

    B: BufMut, 

Encodes the message to a buffer.

pub fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

pub fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

pub fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes a length-delimited instance of the message from the buffer.

pub fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes an instance of the message from a buffer, and merges it into self.

pub fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<Datum> for Datum

fn eq(&self, other: &Datum) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Datum) -> bool

This method tests for !=.
