}

Trait for dynamically typed values that support comparison and display.

Implementations are provided for common Rust types including String, &'static str, i32, i64, f64, bool, and usize.

Required Methods

fn compare(&self, other: &dyn DataTableDynValue) -> Ordering

Compares this value to another for sorting.

Parameters

• other: The other value to compare against.

Returns

• Ordering: The comparison result.

fn clone_box(&self) -> Box<dyn DataTableDynValue>

Clone into a boxed trait object.

Returns

• Box<dyn DataTableDynValue>: A boxed clone of this value.

fn as_any(&self) -> &(dyn Any + 'static)

Returns the value as Any for downcasting.

Returns

• &dyn Any: A reference to the value as Any.

Provided Methods

fn as_string(&self) -> String

Returns the value as a string for filtering.

fn contains_str(&self, needle: &str) -> bool

Returns true if this value contains the given substring (case-insensitive).

Parameters

• needle: The substring to search for.

Returns

• bool: Whether the value contains the substring.

fn as_f64(&self) -> Option<f64>

Returns an optional f64 representation for numeric comparisons.

Returns

• Option<f64>: The numeric value if available.
