Type Alias GroupOfChildren

pub type GroupOfChildren<M> = HashMap<ChildProcessId, ChildInfoMeta<M>>;

Implementing Deref and DerefMut doesn’t improve ergonomics for accessing the tuple’s field by numeric index. For that we have to put the dereferencing asterisk and the struct instance into parenthesis, e.g.

let wrap: ChildInfoMetaWrap = …; meta = (*wrap).2;

So we may just as well use

let wrap: ChildInfoMetaWrap = …; meta = wrap.0.2;

• a little easier to type and read. However, we really want to use our named accessor methods.

But dereferencing with asterisk is ergonomic when we need to cast the struct back to the tuple type. Group of active (running) Child processes.

NOT std::collections::HashSet, because that makes referencing the items less efficient.

Keys are results of ChildProcess’s id() method.

Aliased Type

struct GroupOfChildren<M> { /* private fields */ }
