Mutable methods for core::FileNodeIterator

Required Methods

fn as_raw_mut_FileNodeIterator(&mut self) -> *mut c_void

Provided Methods

fn incr(&mut self) -> Result<FileNodeIterator>

moves iterator to the next node

unsafe fn read_raw( &mut self, fmt: &str, vec: *mut c_void, len: size_t ) -> Result<FileNodeIterator>

Reads node elements to the buffer with the specified format.

Usually it is more convenient to use operator >> instead of this method.

Parameters

• fmt: Specification of each array element. See [format_spec] “format specification”
• vec: Pointer to the destination array.
• len: Number of bytes to read (buffer size limit). If it is greater than number of remaining elements then all of them will be read.

C++ default parameters

• len: (size_t)INT_MAX
