Enum CastType 

pub enum CastType {
    Int,
    Float,
    Bool,
    String,
    Timestamp,
}

Available on crate feature transform-cast only.

Target type for RecordTransform::Cast.

Coerces a JSON value to the requested concrete type. Timestamp parses RFC 3339 / ISO 8601 strings and normalises them back to RFC 3339 (so "2026-05-28T00:00:00Z" round-trips unchanged but "2026-05-28T00:00:00+00:00" becomes the canonical form).

Variants

Int

64-bit signed integer (i64).

Float

64-bit float (f64).

Bool

Boolean. Accepts true/false/1/0 (case-insensitive) when the source value is a string.

String

String. Numbers and booleans are stringified via to_string().

Timestamp

RFC 3339 timestamp, returned as a normalised RFC 3339 string.

Trait Implementations

impl Clone for CastType

fn clone(&self) -> CastType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CastType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CastType

fn deserialize<__D>( __deserializer: __D, ) -> Result<CastType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for CastType

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 CastType

fn eq(&self, other: &CastType) -> 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 CastType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
