Enum DiffWarning 

pub enum DiffWarning {
    PrimaryKeyChange {
        table: String,
        column: String,
        new_value: bool,
    },
    AutoincrementChange {
        table: String,
        column: String,
        new_value: bool,
    },

        table: String,
        old_order: Vec<String>,
        new_order: Vec<String>,
    },
}

Informational warnings about changes that the diff engine detected but cannot (or should not) translate into DDL operations automatically.

Variants

PrimaryKeyChange

A column’s primary key status changed. This typically requires table recreation on most databases.

Fields

table: String

Table name.

column: String

Column name.

new_value: bool

New value of the primary_key flag.

AutoincrementChange

A column’s autoincrement status changed. Most databases cannot alter this without recreating the table.

Fields

table: String

Table name.

column: String

Column name.

new_value: bool

New value of the autoincrement flag.

ColumnOrderChanged

The relative ordering of columns changed. Most databases cannot reorder columns without recreating the table.

Fields

table: String

Table name.

old_order: Vec<String>

Column names in the old order.

new_order: Vec<String>

Column names in the new order.

Trait Implementations

impl Clone for DiffWarning

fn clone(&self) -> DiffWarning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiffWarning

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

Formats the value using the given formatter.

impl PartialEq for DiffWarning

fn eq(&self, other: &DiffWarning) -> 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.
