Struct ColumnValue 

#[non_exhaustive]
pub struct ColumnValue {
    pub metadata: Option<ValueMetadata>,
    pub value: Option<Value>,
    /* private fields */
}

LINT.IfChange(stats_data) Value of the column based on data type.

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.

metadata: Option<ValueMetadata>

value: Option<Value>

Implementations
