Enum NumericConversionPolicy 

pub enum NumericConversionPolicy {
    Exact,
    Lossy,
}

Controls whether numeric conversions must preserve the source value.

Self::Exact rejects fractional truncation, integer-to-float rounding, and duration unit remainders. Self::Lossy permits the documented conversion for each target family but still rejects non-finite or out-of-range results where no target value exists.

Variants

Exact

Reject conversions that require truncation, rounding, or precision loss.

Lossy

Permit the explicitly documented lossy conversion behavior.

Implementations

impl NumericConversionPolicy

pub const fn env_friendly() -> Self

Returns the numeric policy used for environment-variable input.

Environment variables are textual, but that does not imply permission to truncate or round their numeric values. The profile therefore uses exact conversion today while keeping that decision local to this type.

Returns

The numeric conversion policy for environment-variable values.
