Struct SchemaDiff 

pub struct SchemaDiff {
    pub added: Vec<Field>,
    pub dropped: Vec<String>,
}

The schema delta between a module’s declared fields and its migrated columns.

Fields

added: Vec<Field>

Declared fields with no column yet — safe, additive ADD COLUMN.

dropped: Vec<String>

Columns present in the migrations but no longer declared — potential drops (or the old half of a rename). Reported; only emitted under --force.

Implementations

impl SchemaDiff

pub fn is_empty(&self) -> bool

Trait Implementations

impl Debug for SchemaDiff

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

Formats the value using the given formatter.

impl Default for SchemaDiff

fn default() -> SchemaDiff

Returns the “default value” for a type.

impl Eq for SchemaDiff

impl PartialEq for SchemaDiff

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