[−][src]Struct scfg::Directive
A single scfg directive, containing any number of parameters, and possibly one child block.
Implementations
impl Directive
[src]
pub fn new() -> Self
[src]
Creates a new empty directive.
pub fn params(&self) -> &[String]
[src]
Get this directive's parameters
pub fn append_param(&mut self, param: impl Into<String>) -> &mut Self
[src]
Appends the supplied parameter. Returns &mut self
to support method
chaining.
Note
This does not validate that param
is a legal scfg word. It is possible to create
unparsable documents should param
contain control characters or newlines.
pub fn clear_params(&mut self)
[src]
Clears all parameters from this directive.
pub fn child(&self) -> Option<&Scfg>
[src]
Get this directive's child, if there is one.
pub fn take_child(&mut self) -> Option<Scfg>
[src]
Takes this directive's child, leaving it with None
.
pub fn get_or_create_child(&mut self) -> &mut Scfg
[src]
Returns the child, optionally creating it if it does not exist.
let mut directive = Directive::new(); assert!(directive.child().is_none()); directive.get_or_create_child(); assert!(directive.child().is_some());
