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: &FileNodeIterator) -> Result<()>

source

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

moves iterator to the next node

source

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
source

unsafe fn read_raw_def( &mut self, fmt: &str, vec: *mut c_void ) -> 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.
Note

This alternative version of FileNodeIteratorTrait::read_raw function uses the following default values for its arguments:

  • len: (size_t)INT_MAX
