Enum SchemaMode 

pub enum SchemaMode {
    Verify,
    DryRun,
    Execute,
}

Controls schema migration behavior at startup. Controlled by TEAQL_SCHEMA. Default is Verify — the safest option for production.

Variants

Verify

Check that the database schema matches the model. If there is any mismatch, print the details and exit immediately. This is the DEFAULT — no env var needed for the safest behavior.

DryRun

Print the SQL statements that would be executed to bring the schema in sync, but do NOT execute them. For DBA review.

Execute

Actually execute schema changes (CREATE TABLE, ALTER TABLE ADD COLUMN, CREATE INDEX, seed data). Use in development and CI only.

Trait Implementations

impl Clone for SchemaMode

fn clone(&self) -> SchemaMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SchemaMode

impl Debug for SchemaMode

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

Formats the value using the given formatter.

impl Default for SchemaMode

fn default() -> Self

Returns the “default value” for a type.

impl Eq for SchemaMode

impl PartialEq for SchemaMode

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