Member Function Documentation

size()

ETL_NODISCARD ETL_CONSTEXPR14 size_t etl::ibase64_decoder::size ( ) const

inline

Returns the size of the output buffer. This only returns a useful value if a callback has not been set or called.

span()

ETL_NODISCARD ETL_CONSTEXPR14 span_type etl::ibase64_decoder::span ( ) const

inline

Get a span of the output data. This only returns a useful span if a callback has not been set or called.
