Struct Moniker

pub struct Moniker { /* private fields */ }

Moniker describes the identity of a component instance in terms of its path relative to the root of the component instance tree.

Display notation: “.”, “name1”, “name1/name2”, …

Implementations

impl Moniker

pub fn new(path: &[ChildName]) -> Self

pub fn path(&self) -> &[ChildName]

pub fn parse<T: AsRef<str>>(path: &[T]) -> Result<Self, MonikerError>

pub fn parse_str(input: &str) -> Result<Self, MonikerError>

pub fn concat(&self, other: &Moniker) -> Self

Concatenates other onto the end of this moniker.

pub fn has_prefix(&self, prefix: &Moniker) -> bool

Indicates whether this moniker is prefixed by prefix.

pub fn root() -> Self

pub fn leaf(&self) -> Option<&ChildName>

Returns the last child of this moniker if this is not the root moniker.

pub fn is_root(&self) -> bool

pub fn parent(&self) -> Option<Self>

Creates a new moniker with the last child removed. Returns None if this is the root moniker.

pub fn child(&self, child: ChildName) -> Self
