Struct Context

pub struct Context<K, V> { /* private fields */ }

A module with a path to an open submodule.

Implementations

impl<K: Ord, V: Default> Context<K, V>

pub fn new() -> Self

Create a new context with a default root module as current open module.

pub fn open_or_default(&mut self, name: K)

Open a default module inside the previously open module.

impl<K: Ord, V> Context<K, V>

pub fn open_or(&mut self, name: K, module: Module<K, V>)

Open a module inside the previously open module.

Use the provided module if the module with the given name does not exist.

pub fn open_or_else(&mut self, name: K, f: impl FnOnce() -> Module<K, V>)

Open a module inside the previously open module.

Use the provided closure if the module with the given name does not exist.

pub fn insert(&mut self, name: K, module: Module<K, V>) -> Option<Module<K, V>>

Insert a module into the currently open module.

pub fn remove(&mut self, name: &K) -> Option<Module<K, V>>

Remove a module from the currently open module.

pub fn close(&mut self) -> bool

Close the currently open module.

Return false if the current open module is the root module.

pub fn find<'a, 'q, Q, I>( &'a self, path: I, ) -> impl Iterator<Item = &'a Module<K, V>>

where K: Borrow<Q>, Q: Ord + ?Sized + 'q, I: Iterator<Item = &'q Q> + Clone,

Find modules matching the given path from the currently open module.

impl<K, V> Context<K, V>

pub fn get(&self) -> &Module<K, V>

Return a reference to the currently open module.

pub fn get_mut(&mut self) -> &mut Module<K, V>

Return a mutable reference to the currently open module.

pub fn get_path(&self) -> impl Iterator<Item = &K>

Return the path of the currently open module.

Trait Implementations

impl<K: Ord, V: Default> Default for Context<K, V>

fn default() -> Self

impl<K: Ord, V> From<Context<K, V>> for Module<K, V>

fn from(ctx: Context<K, V>) -> Self

Converts to this type from the input type.

impl<K, V> From<Module<K, V>> for Context<K, V>

fn from(root: Module<K, V>) -> Self

Converts to this type from the input type.
