parameter type T may not live long enough - when the counted struct is generic

[peter-lyons-kehl]

Somewhere between v. 2 and 3.0.1 countme changed so the following

#[derive(PartialEq)]
pub struct SegmentedBuf<T> {
    _c: countme::Count<Self>,
    pub(crate) bufs: SmallVec<[T; 4]>,
    pos: usize,
    offset: usize,
    read_pos: usize,
    read_offset: usize,
    segment_size: usize,
}

fails with

error[E0310]: the parameter type `T` may not live long enough

FYI the error comes from https://github.com/logdna/logdna-rust/blob/main/src/segmented_buffer.rs#L103= (after updating the version in Cargo.toml). I'm not familiar with logdna-rust yet, but I'll try to narrow this issue down.
(The same error happens with Rust 1.61.0 and 1.63.0-nightly.)

Ahah, as per "it means it doesn't/can't contain any non-static references. Meaning it can only have owned types and/or 'static references." (from https://www.reddit.com/r/rust/comments/o9w6rl/comment/h3dszio/?utm_source=reddit&utm_medium=web2x&context=3).

May I suggest a note about that in README.md, please. Especially so because this use of 'static is infrequent, and cargoc's message is not helpful either.
