Enum SettingValue 

pub enum SettingValue {
    Int(i64),
    Bool(bool),
    Float(f64),
    String(String),
}

Supported value types for ClickHouse query settings.

This enum represents the possible data types for a Setting’s value, including integers, booleans, floats, and strings. It implements From for various Rust primitive types (e.g., i32, &str, f64) to simplify setting creation.

Variants

• Int(i64): A 64-bit integer (e.g., for max_threads).
• Bool(bool): A boolean (e.g., for allow_experimental_features).
• Float(f64): A 64-bit float (e.g., for quantile).
• String(String): A string (e.g., for default_format).

Example

use clickhouse_arrow::query::settings::SettingValue;

let int_value: SettingValue = 8_i32.into();
let bool_value: SettingValue = true.into();
let string_value: SettingValue = "JSON".to_string().into();
assert!(matches!(int_value, SettingValue::Int(8)));

Variants

Int(i64)

Bool(bool)

Float(f64)

String(String)
