fn elname(&self) -> String

fn set_elname(&mut self, val: &str)

fn open(&mut self, filename: &str, flags: i32, encoding: &str) -> Result<bool>

Opens a file.

fn is_opened(&self) -> Result<bool>

Checks whether the file is opened.

fn release(&mut self) -> Result<()>

Closes the file and releases all the memory buffers.

fn release_and_get_string(&mut self) -> Result<String>

fn get_first_top_level_node(&self) -> Result<FileNode>

Returns the first element of the top-level mapping. ## Returns The first element of the top-level mapping.

fn root(&self, streamidx: i32) -> Result<FileNode>

Returns the top-level mapping ## Parameters * streamidx: Zero-based index of the stream. In most cases there is only one stream in the file. However, YAML supports multiple streams and so there can be several. ## Returns The top-level mapping.

fn get(&self, nodename: &str) -> Result<FileNode>

Returns the specified element of the top-level mapping. ## Parameters * nodename: Name of the file node. ## Returns Node with the given name.

fn get_node(&self, nodename: &str) -> Result<FileNode>

Returns the specified element of the top-level mapping. ## Parameters * nodename: Name of the file node. ## Returns Node with the given name.
