Enum NumberSchema

pub enum NumberSchema {
    Integer {
        integer: IntegerSchema,
        scale: f64,
        offset: f64,
    },
    Float {
        byteorder: ByteOrder,
    },
    Double {
        byteorder: ByteOrder,
    },
}

The number schema describes a numeric value (further information on the module’s documentation).

Implementations

impl NumberSchema

pub fn default_length() -> usize

Default length is 8 bytes like a double-precision floating-point number.

pub fn default_scale() -> f64

Default scale is neutral, i.e. 1.0.

pub fn default_offset() -> f64

Default offset is neutral, i.e. 0.0.

pub fn to_binary_value(&self, value: f64) -> i64

Apply scale and offset to the value.

pub fn from_binary_value(&self, value: f64) -> f64

Apply scale and offset to the value.

pub fn length(&self) -> usize
