bson_iter_key_len()#

Synopsis#

uint32_t
bson_iter_key_len (const bson_iter_t *iter);

Parameters#

iter: A bson_iter_t.

Description#

Fetches the length of the key for the current element observed by iter. This is a constant time computation, and therefore faster than calling strlen() on a key returned by bson_iter_key().

Returns#

An integer representing the key length.
