Module take 

take — take the value out of an Option field

The take method is only generated for Option<T> fields. It calls Option::take on the field, returning Option<T> and leaving None in its place. Non-option fields are silently skipped.

On enums, take is only generated for full-coverage Option<T> fields. See enums.

struct Session {
    /// auth token, consumed on first use
    token: Option<String>,

    /// cached response, cleared after reading
    cached_response: Option<Vec<u8>>,
}

// GENERATED
impl Session {
    ///Takes auth token, consumed on first use, leaving a None in its place
    pub fn take_token(&mut self) -> Option<String> {
        self.token.take()
    }
    ///Takes cached response, cleared after reading, leaving a None in its place
    pub fn take_cached_response(&mut self) -> Option<Vec<u8>> {
        self.cached_response.take()
    }
