method

Backend.Put

func (backend *Backend) Put(
	ctx context.Context,
	key string,
	source io.Reader,
	size int64,
	_ string,
) (result error)

Atomically and durably write an object with its declared size.

Source adapters/storage/local/local.go:139

@param ctx: The ctx value.
@param key: The key value.
@param source: The source value.
@param size: The size value.
@param _: The _ value.
@returns: The declared result.

The local backend does not persist contentType. It rejects traversal/path-shaped object keys and size mismatches, and preserves an existing object when a replacement fails.
