Function json_to_variant

pub fn json_to_variant(
    json: &str,
    builder: &mut VariantBuilder,
) -> Result<(), ArrowError>

Converts a JSON string to Variant using [VariantBuilder]. The resulting value and metadata buffers can be extracted using builder.finish()

Arguments

• json - The JSON string to parse as Variant.
• variant_builder - Object of type VariantBuilder used to build the vatiant from the JSON string

Returns

• Ok(()) if successful
• Err with error details if the conversion fails
