Trait influxdb::Query

pub trait Query {
    fn build(&self) -> Result<ValidQuery, Error>;
    fn get_type(&self) -> QueryType;
}

Required methods

fn build(&self) -> Result<ValidQuery, Error>

Builds valid InfluxSQL which can be run against the Database. In case no fields have been specified, it will return an error, as that is invalid InfluxSQL syntax.

Examples

use influxdb::{Query, Timestamp};

let invalid_query = Query::write_query(Timestamp::NOW, "measurement").build();
assert!(invalid_query.is_err());

let valid_query = Query::write_query(Timestamp::NOW, "measurement").add_field("myfield1", 11).build();
assert!(valid_query.is_ok());

fn get_type(&self) -> QueryType

Implementations

impl dyn Query

pub fn write_query<S>(timestamp: Timestamp, measurement: S) -> WriteQuery where
    S: Into<String>, 

Returns a WriteQuery builder.

Examples

use influxdb::{Query, Timestamp};

Query::write_query(Timestamp::NOW, "measurement"); // Is of type [`WriteQuery`](crate::WriteQuery)

pub fn raw_read_query<S>(read_query: S) -> ReadQuery where
    S: Into<String>, 

Returns a ReadQuery builder.

Examples

use influxdb::Query;

Query::raw_read_query("SELECT * FROM weather"); // Is of type [`ReadQuery`](crate::ReadQuery)
