Struct FormatSpec 

pub struct FormatSpec {
    pub decimal_places: u8,
    pub integer_places: u8,
}

Compiled form of an SRD-40b format: declaration. The only field that matters at value-sanitiser time is decimal_places; the integer-side layout is recorded for diagnostic display but not enforced on the value.

Fields

decimal_places: u8

Number of decimal places to round to. 0 means “round to integer.”

integer_places: u8

Number of placeholder characters before the decimal point. Layout-only; not applied to the value.

Implementations

impl FormatSpec

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