Struct ql2::Query

pub struct Query {
    pub type: Option<i32>,
    pub query: Option<Term>,
    pub token: Option<i64>,
    pub obsolete_noreply: Option<bool>,
    pub accepts_r_json: Option<bool>,
    pub global_optargs: Vec<AssocPair>,
}

You send one of:

• A [START] query with a Term to evaluate and a unique-per-connection token.
• A [CONTINUE] query with the same token as a [START] query that returned [SUCCESS_PARTIAL] in its Response.
• A [STOP] query with the same token as a [START] query that you want to stop.
• A [NOREPLY_WAIT] query with a unique per-connection token. The server answers with a [WAIT_COMPLETE] Response.
• A [SERVER_INFO] query. The server answers with a [SERVER_INFO] Response.

Fields

type: Option<i32>

query: Option<Term>

A Term is how we represent the operations we want a query to perform.

only present when [type] = [START]

token: Option<i64>

obsolete_noreply: Option<bool>

This flag is ignored on the server. noreply should be added to global_optargs instead (the key “noreply” should map to either true or false).

accepts_r_json: Option<bool>

If this is set to true, then Datum values will sometimes be of [DatumType] [R_JSON] (see below). This can provide enormous speedups in languages with poor protobuf libraries.

global_optargs: Vec<AssocPair>

Implementations

impl Query

pub fn type(&self) -> QueryType

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: QueryType)

Sets type to the provided enum value.

pub fn token(&self) -> i64

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

pub fn obsolete_noreply(&self) -> bool

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

pub fn accepts_r_json(&self) -> bool

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

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl Default for Query

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Query

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>,

fn encoded_len(&self) -> usize

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

fn clear(&mut self)

Clears the message, resetting all fields to their default.

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<Query> for Query

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

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

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

This method tests for !=.
