Struct NullConversionConfig 

#[non_exhaustive]
pub struct NullConversionConfig {
    pub enabled: bool,
    pub extra_tokens: SmallVec<[String; 2]>,
}

Configuration for null-string detection, used by TypeConversionConfig.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

enabled: bool

Enable null-string detection and conversion

extra_tokens: SmallVec<[String; 2]>

Additional strings recognized as null, beyond the built-in list ("null", "NULL", "Null", "nil", "NIL", "Nil", "none", "NONE", "None", "N/A", "n/a", "NA", "na"). Additive only – cannot narrow the built-in list. Matched exactly (case-sensitive).
