pub fn install_default()Expand description
Install the global defaults provided by the facade crate.
This function is safe to call multiple times. It registers enabled services and installs the default HTTP transport when the corresponding feature is enabled.
ยงProcess-wide HTTP transport
When auto-register-services is enabled, a process constructor calls this
function before main. If a default HTTP transport feature is also enabled,
that transport occupies the process-wide default because
HttpTransporter::install_default uses first-installed-wins semantics.
Applications that need to install their own process-wide transport should
disable auto-register-services, call init_default_registry explicitly
when URI-based construction is needed, and install the transport themselves.
Per-operator transports can be configured regardless of this setting.
