Enum KeyCollision 

pub enum KeyCollision {
    Error,
    Suffix,
}

Available on crate feature transform-keys-case only.

Policy for RecordTransform::KeysCase when two distinct source keys re-case to the same name (common on wide, vendor-namespaced sources such with custom-field suffixes, e.g. AccountId__c + Account_Id__c → account_id_c).

Variants

Error

Fail the record with a Transform error naming the colliding key (the default — never silently drops a column).

Suffix

Disambiguate colliding keys by appending _2, _3, … in original key order (first occurrence keeps the base name). Deterministic and order-stable, mirroring z3z1ma target-bigquery’s add_underscore_when_invalid.

Trait Implementations

impl Clone for KeyCollision

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for KeyCollision

impl Debug for KeyCollision

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

Formats the value using the given formatter.

impl Default for KeyCollision

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for KeyCollision

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

impl Eq for KeyCollision

impl JsonSchema for KeyCollision

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
