Enum NonFiniteFloatPolicy 

#[non_exhaustive]
pub enum NonFiniteFloatPolicy {
    PassThrough,
    Reject,
    AsString,
}

Handling of non-finite floats in deserialize_any.

By default, non-finite floats are rejected. This policy applies to inferred values, including Serde’s buffering for untagged enums and flattened fields. Direct f32/f64 deserialization is unaffected.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PassThrough

Pass NaN and positive/negative infinity to the visitor as f64 values.

The receiving visitor determines how to represent them. For example, serde_json::Value converts them to Null without returning an error.

Reject

Return crate::Error::NonFiniteFloat before calling the visitor.

AsString

Pass canonical strings (.nan, .inf, -.inf) to the visitor.
