Enum OnDrift 

pub enum OnDrift {
    Warn,
    Evolve,
    Ignore,
    Quarantine,
    Fail,
}

What to do when drift is detected.

Variants

Warn

Detect + emit a metric and a one-shot log; write the page unchanged.

Evolve

Apply additive/widening DDL to the destination, then write.

Ignore

Drop unknown (non-destination) fields from every record; write the rest.

Quarantine

Route the records that exhibit the drift to the DLQ; write the rest.

Fail

Raise FaucetError::SchemaDrift and abort.

Trait Implementations

impl Clone for OnDrift

fn clone(&self) -> OnDrift

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OnDrift

impl Debug for OnDrift

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

Formats the value using the given formatter.

impl Default for OnDrift

fn default() -> OnDrift

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OnDrift

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for OnDrift

impl JsonSchema for OnDrift

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for OnDrift

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

impl Serialize for OnDrift

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
