Function fuchsia_decode_log_messages_to_struct 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn fuchsia_decode_log_messages_to_struct(
    msg: *const u8,
    size: usize,
    expect_extended_attribution: bool,
) -> LogMessages<'static>

Safety

Same as for std::slice::from_raw_parts. Summarizing in terms of this API:

• msg must be valid for reads for size, and it must be properly aligned.
• msg must point to size consecutive u8 values.
• ‘msg’ must outlive the returned LogMessages struct, and must not be free’d until fuchsia_free_log_messages has been called.
• The size of the slice must be no larger than isize::MAX, and adding that size to data must not “wrap around” the address space. See the safety documentation of pointer::offset. If identity is provided, it must contain a valid moniker and URL.

The returned LogMessages may be free’d with fuchsia_free_log_messages(log_messages). Free’ing the LogMessages struct does the following, in this order:

• Frees memory associated with each individual log message
• Frees the bump allocator itself (and everything allocated from it), as well as the message array itself. If a malformed message is passed, returns nullptr.
