Struct aces::Context

pub struct Context { /* fields omitted */ }

A representation of shared state.

This is an umbrella type which, currently, includes a collection of Atoms and two symbol tables, one for structure names, and another for node names.

For usage, see ContextHandle type, Contextual trait and InContext struct.

Methods

impl Context

pub fn new_as_handle() -> ContextHandle

Creates a new Context instance and returns a corresponding ContextHandle.

Calling this method is the only public way of creating new Context instances.

pub fn share_node_name<S: AsRef<str>>(&mut self, node_name: S) -> NodeID

pub fn get_node_name(&self, node_id: NodeID) -> Option<&str>

pub fn get_node_id<S: AsRef<str>>(&self, node_name: S) -> Option<NodeID>

pub fn share_port(&mut self, port: &mut Port) -> PortID

pub fn share_link(&mut self, link: &mut Link) -> LinkID

pub fn get_port(&self, port_id: PortID) -> Option<&Port>

pub fn get_port_mut(&mut self, port_id: PortID) -> Option<&mut Port>

pub fn get_link(&self, link_id: LinkID) -> Option<&Link>

pub fn get_link_mut(&mut self, link_id: LinkID) -> Option<&mut Link>

pub fn get_antiport_id(&self, port_id: PortID) -> Option<PortID>

impl Context

pub fn with<'a, T: Contextual>(&'a self, thing: &'a T) -> InContext<'a, T>

pub fn with_mut<'a, T: Contextual>(
    &'a self,
    thing: &'a mut T
) -> InContextMut<'a, T>

pub fn with_docked<'a, T: Contextual>(
    &'a self,
    face: Face,
    thing: &'a T
) -> InContext<'a, T>

pub fn with_docked_mut<'a, T: Contextual>(
    &'a self,
    face: Face,
    thing: &'a mut T
) -> InContextMut<'a, T>

Trait Implementations

impl PartialEq<Context> for Context

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Eq for Context

impl Debug for Context

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
