Struct Namespace 

Source 
pub struct Namespace { /* private fields */ }
Expand description

The namespace of a component instance.

Namespaces may be represented as a collection of directory client endpoints and their corresponding unique paths, so called “flat representation”. In this case each path must be a valid cm_types::NamespacePath, and no path can be a parent of another path.

See https://fuchsia.dev/fuchsia-src/concepts/process/namespaces for the definition of namespaces of a process. The namespace of a component largely follows except that some more characters are disallowed (c.f. cm_types::NamespacePath documentation).
