Struct slr_config::ConfigElement

pub struct ConfigElement { /* fields omitted */ }

A configuration element.

Methods

impl ConfigElement

fn new_table() -> ConfigElement

Creates a new empty table.

fn new_value<T: ToString>(value: T) -> ConfigElement

Creates a new value.

fn new_array() -> ConfigElement

Creates a new array.

fn from_source<'l>(source: &mut Source<'l>) -> Result<ConfigElement, Error>

Parses a source and returns a table. The source will be reset by this operation, and must not be used with any spans created from a previous parsing done with that source.

fn from_str(src: &str) -> Result<ConfigElement, Error>

Parses a source and returns a table.

fn from_source_with_init<'l, 'm>(&mut self,
                                 source: &'m mut Source<'l>)
                                 -> Result<(), Error>

Updates the elements in this table with new values parsed from source. If an error occurs, the contents of this table are undefined. The source will be reset by this operation, and must not be used with any spans created from a previous lexing done with that source.

fn from_str_with_init(&mut self, src: &str) -> Result<(), Error>

Updates the elements in this table with new values parsed from source. If an error occurs, the contents of this table are undefined.

fn kind(&self) -> &ConfigElementKind

Returns the kind of this element.

fn kind_mut(&mut self) -> &mut ConfigElementKind

Returns the kind of this element.

fn span(&self) -> Span

Returns the span associated with this element.

fn as_table(&self) -> Option<&BTreeMap<String, ConfigElement>>

If this is a table, returns a pointer to its contents.

fn as_table_mut(&mut self) -> Option<&mut BTreeMap<String, ConfigElement>>

If this is a table, returns a pointer to its contents.

fn as_value(&self) -> Option<&String>

If this is a value, returns a pointer to its contents.

fn as_value_mut(&mut self) -> Option<&mut String>

If this is a value, returns a pointer to its contents.

fn as_array(&self) -> Option<&Vec<ConfigElement>>

If this is an array, returns a pointer to its contents.

fn as_array_mut(&mut self) -> Option<&mut Vec<ConfigElement>>

If this is an array, returns a pointer to its contents.

fn insert<T: ToString>(&mut self, name: T, elem: ConfigElement)

Insert an element into a table or an array. Panics if self is a value. name is ignored if self is an array.

fn print<W: Write>(&self,
                   name: Option<&str>,
                   is_root: bool,
                   printer: &mut Printer<W>)
                   -> Result<(), Error>

Outputs the string representation of this element into into a printer.
