Struct TermLength 

pub struct TermLength(/* private fields */);

Number of consecutive views in which a leader remains stable (a “term”).

When the term length is 1, every view is its own term and each view has an independently elected leader. When greater than 1, views are grouped into terms and the same leader serves for every view in the term.

Unlike ViewDelta, which represents an offset added to or subtracted from a view, a term length is a period that partitions the view space. It is always non-zero.

Consensus-Critical

The term length is consensus-critical configuration (like the namespace or participant set): it is local, is not carried by any vote or certificate, and nothing in the protocol detects a mismatch. All participants must configure the same value. Term boundaries determine which views a nullification covers, leader election, and when finalize votes are withheld, so mismatched participants silently disagree on view transitions and vote safety without producing any fault evidence. Only change the term length when all participants change it together (e.g., at an epoch boundary).

Longer terms also widen the window of unverified votes a participant may buffer while finalization stalls: votes are accepted for any view between the highest finalized view and the current view, and the current view advances by up to a full term per nullification.

Implementations

impl TermLength

pub const MAX: Self

The maximum term length. Lengths are stored as a u32, bounding term arithmetic (like View::next_term_start) away from u64 overflow for any realistic view.

pub const ONE: Self

A term length of one view (every view has an independently elected leader).

pub const fn new(length: NonZeroU32) -> Self

Creates a new term length.

pub const fn get(self) -> u64

Returns the number of views per term.
