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.
