bool nlohmann::detail::binary_reader< BasicJsonType, InputAdapterType, SAX >::get_bson_binary ( const NumberType  len, binary_t &  result  )

inlineprivate

Parses a byte array input of length len from the BSON input.

Parameters

[in]	len	The length of the byte array to be read.
[in,out]	result	A reference to the binary variable where the read array is to be stored.

Template Parameters

NumberType

The type of the length len

Precondition

len >= 0

Returns

true if the byte array was successfully parsed
