Function FLEncoder_WriteRaw 

pub unsafe extern "C" fn FLEncoder_WriteRaw(
    arg1: FLEncoder,
    arg2: FLSlice,
) -> bool

Writes raw data directly to the encoded output. (This is not the same as \ref FLEncoder_WriteData, which safely encodes a blob.) @warning Do not call this unless you really know what you’re doing … it’s quite unsafe, and only used for certain advanced purposes.
