Module variant 

Structs

VariantRef

Borrowed value of the variant type.

VariantVal

Owned value of the variant type.

CANONICAL_NAN_F32 🔒

Functions

append_datum_value 🔒

append_decimal 🔒

append_float64 🔒

append_json_value 🔒

append_struct 🔒

append_variant_value 🔒

Re-encodes a variant value with the canonical builder, normalizing floats to their canonical bit patterns.

canonical_builder 🔒

collect_datum_field_names 🔒

collect_json_field_names 🔒

collect_variant_field_names 🔒

collect_variant_field_names_inner 🔒

Collects object field names for the canonical dictionary.

contains_non_finite_float 🔒

Returns whether the variant contains a non-finite float. Read errors also count so that the lossy path, which reports them, is taken.

expect_serialized_value 🔒

jsonb_to_json_value 🔒

Parses a jsonb value through its text form. The round trip is deliberate: serde_json’s parser enforces a nesting limit, while walking jsonbb directly would recurse without a bound.

non_finite_to_json 🔒

normalize_double 🔒

See normalize_float.

normalize_float 🔒

Normalizes a float to its canonical bit pattern: a single NaN representation and -0.0 collapsed to +0.0.

parse_path 🔒

reject_duplicate_field 🔒

Variant objects require unique field names, but RisingWave struct types allow duplicates. Callers iterate fields in name order, so comparing against the previous name suffices.

split_serialized_value 🔒

variant_to_json_value_lossy 🔒

Converts a variant to a serde_json::Value, rendering non-finite floats as the strings "NaN" / "Infinity" / "-Infinity", following to_jsonb on float types.
