Function decodeDag

src/simplicity/deserialize.c:155–163

Decode a Simplicity DAG consisting of 'len' nodes from 'stream' into 'dag'. * Returns 'SIMPLICITY_ERR_DATA_OUT_OF_RANGE' if some node's child isn't a reference to one of the preceding nodes. * Returns 'SIMPLICITY_ERR_FAIL_CODE' if the encoding of a fail expression is encountered * (all fail subexpressions ought to have been pruned prior to deserialization). * Returns 'SIMPLICITY_ERR_RESERVED

 *               NULL != stream
