func ConvertAnthropicV1ToBetaRequest added in v0.260514.1 

func ConvertAnthropicV1ToBetaRequest(req *anthropic.MessageNewParams) *anthropic.BetaMessageNewParams

ConvertAnthropicV1ToBetaRequest projects an Anthropic v1 MessageNewParams onto the Beta MessageNewParams shape. Beta's wire format is a strict structural superset of v1's (same field names and shapes; Beta only adds optional fields), so a v1 request's own JSON round-trips losslessly into the Beta struct — every block type (text, image, tool_use, tool_result, documents, cache_control, ...) survives without hand-maintained per-type conversion. This previously did a field-by-field Go copy that silently dropped tool_result content and image data; the round-trip has no such gaps and needs no updates when the SDK adds new block types.

This compatibility wrapper keeps the historical nil-on-failure behavior for context-extraction callers. Protocol boundaries that need an actionable error should use ConvertAnthropicV1ToBetaRequestWithError.
