Struct ValueTransformation 

#[non_exhaustive]
pub struct ValueTransformation {
    pub filter: Option<Filter>,
    pub action: Option<Action>,
    /* private fields */
}

Description of data transformation during migration as part of the ConditionalColumnSetValue.

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.

filter: Option<Filter>

action: Option<Action>

Trait Implementations

impl Clone for ValueTransformation

fn clone(&self) -> ValueTransformation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueTransformation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ValueTransformation

fn default() -> ValueTransformation

Returns the “default value” for a type.

impl Message for ValueTransformation

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ValueTransformation

fn eq(&self, other: &ValueTransformation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
