Mutable methods for core::FileNodeIterator

Required Methods§

Source

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

Provided Methods§

Source

fn set(&mut self, it: &impl FileNodeIteratorTraitConst) -> Result<()>

Source

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

moves iterator to the next node

Source

fn read_raw(&mut self, fmt: &str, vec: &mut [u8]) -> 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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
