Enum DrainRequestMethods 

pub enum DrainRequestMethods {
    PostOnly,
    GetOrPost,
}

HTTP methods that the /drainz probe route accepts.

A drain request starts the process shutdown, so the default accepts only POST. Kubernetes preStop.httpGet hooks can send only GET; a deployment that drains through such a hook opts in with Self::GetOrPost.

Variants

PostOnly

Accepts only POST. GET receives 405 Method Not Allowed.

GetOrPost

Accepts GET and POST.

Implementations

impl DrainRequestMethods

pub fn parse(raw: &str) -> Option<Self>

Parses the value of ROCKETMQ_HEALTH_DRAIN_METHODS.

Accepts a comma-separated method list, ignoring case, blanks around methods, and order: POST or GET,POST. Returns None for any other list, including GET alone, since draining must stay reachable by POST.

pub fn allows(self, method: &str) -> bool

Returns whether method may start a drain.

pub const fn allow_header(self) -> &'static str

Returns the value of the Allow header for a rejected drain request.
