Bool, Tinyint, Smallint, Int, Bigint, Float, Double¶

Bool¶

Bool is represented as rust bool

# use scylla::Session;
# use std::error::Error;
# async fn check_only_compiles(session: &Session) -> Result<(), Box<dyn Error>> {
use scylla::IntoTypedRows;

// Insert a bool into the table
let to_insert: bool = true;
session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (to_insert,))
    .await?;

// Read a bool from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(bool,)>() {
        let (bool_value,): (bool,) = row?;
    }
}
# Ok(())
# }

Tinyint¶

Tinyint is represented as rust i8

# extern crate scylla;
# use scylla::Session;
# use std::error::Error;
# async fn check_only_compiles(session: &Session) -> Result<(), Box<dyn Error>> {
use scylla::IntoTypedRows;

// Insert a tinyint into the table
let to_insert: i8 = 123;
session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (to_insert,))
    .await?;

// Read a tinyint from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(i8,)>() {
        let (tinyint_value,): (i8,) = row?;
    }
}
# Ok(())
# }

Smallint¶

Smallint is represented as rust i16

// Insert a smallint into the table
let to_insert: i16 = 12345;
session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (to_insert,))
    .await?;

// Read a smallint from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(i16,)>() {
        let (smallint_value,): (i16,) = row?;
    }
}
# Ok(())
# }

Int¶

Int is represented as rust i32

use scylla::IntoTypedRows;

// Insert an int into the table
let to_insert: i32 = 12345;
session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (to_insert,))
    .await?;

// Read an int from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(i32,)>() {
        let (int_value,): (i32,) = row?;
    }
}
# Ok(())
# }

Bigint¶

Bigint is represented as rust i64

# extern crate scylla;
# use scylla::Session;
# use std::error::Error;
# async fn check_only_compiles(session: &Session) -> Result<(), Box<dyn Error>> {
use scylla::IntoTypedRows;

// Insert a bigint into the table
let to_insert: i64 = 12345;
session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (to_insert,))
    .await?;

// Read a bigint from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(i64,)>() {
        let (bigint_value,): (i64,) = row?;
    }
}
# Ok(())
# }

Float¶

Float is represented as rust f32

# extern crate scylla;
# use scylla::Session;
# use std::error::Error;
# async fn check_only_compiles(session: &Session) -> Result<(), Box<dyn Error>> {
use scylla::IntoTypedRows;

// Insert a float into the table
let to_insert: f32 = 123.0;
session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (to_insert,))
    .await?;

// Read a float from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(f32,)>() {
        let (float_value,): (f32,) = row?;
    }
}
# Ok(())
# }

Double¶

Double is represented as rust f64

# extern crate scylla;
# use scylla::Session;
# use std::error::Error;
# async fn check_only_compiles(session: &Session) -> Result<(), Box<dyn Error>> {
use scylla::IntoTypedRows;

// Insert a double into the table
let to_insert: f64 = 12345.0;
session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (to_insert,))
    .await?;

// Read a double from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(f64,)>() {
        let (double_value,): (f64,) = row?;
