Function get_sanitized_name 

pub fn get_sanitized_name(name: &str) -> MetaString

Sanitizes name into a single process-name segment.

Invalid characters are replaced with underscores, runs of underscores are collapsed into one, and leading and trailing non-alphanumeric characters are trimmed. A name that is already a valid segment is returned unchanged.

Periods are not treated as separators here, unlike in a scoped process name: they are invalid within a segment, so they become underscores like any other invalid character. That is what makes this the right way to fold a dotted value – a hostname, a URL authority – into one segment of a task name. Interpolating such a value directly would instead split it across levels of the process tree.

Examples

assert_eq!(&*get_sanitized_name("app.datadoghq.com"), "app_datadoghq_com");
assert_eq!(&*get_sanitized_name("already_valid"), "already_valid");
