Struct FloatDataType 

pub struct FloatDataType {
    pub precision: FloatPrecision,
}

Approximate floating-point numeric type.

Maps to: REAL/DOUBLE PRECISION (PostgreSQL), REAL/FLOAT (SQL Server), FLOAT/DOUBLE (Snowflake, Databricks), Float32/Float64 (ClickHouse).

Example

use razeri_plugin_contract::DataType;

// Single precision (REAL)
let real = DataType::float();

// Double precision (DOUBLE)
let double = DataType::double();

Fields

precision: FloatPrecision

Precision level (Single or Double).

Implementations

impl FloatDataType

pub fn single() -> Self

Creates a single-precision (4-byte) float type.

Example

use razeri_plugin_contract::data_type::{FloatDataType, FloatPrecision};

let single = FloatDataType::single();
assert_eq!(single.precision, FloatPrecision::Single);

pub fn double() -> Self

Creates a double-precision (8-byte) float type.

Example

use razeri_plugin_contract::data_type::{FloatDataType, FloatPrecision};

let double = FloatDataType::double();
assert_eq!(double.precision, FloatPrecision::Double);
