Enum CoerceError

Source

pub enum CoerceError {
    Overflow,
    PrecisionLoss,
    NaN,
    Zero,
}

Expand description

Error type for coercion failures.

Variants§

§

Overflow

The value cannot fit in the destination range.

§

PrecisionLoss

The destination type cannot represent this value exactly.

§

NaN

The input was NaN and destination disallows it.

§

Zero

Zero is not allowed by the conversion rule.
