Struct GroupRank 

#[non_exhaustive]
pub struct GroupRank {
    pub in_use: bool,
    pub live: bool,
    pub cut: u8,
    pub start: bool,
}

Where a group ranks: how much a pick inside it would narrow the set.

A group is offered first when picking in it cuts the most, which the app measures from its results (tagtree’s rank_groups is one way). Nothing here names a group, so the order moves as the set narrows.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

in_use: bool

A pick sits inside it already.

live: bool

Some pick inside it would still leave results. A dead group says so rather than offering choices that empty the set.

cut: u8

How hard a pick here cuts, from 0 to 100, against the best group on offer: what a bar draws.

start: bool

The best group not yet in use: where a newcomer should start.

Implementations

impl GroupRank

pub const fn cutting(cut: u8) -> Self

A live group cutting cut (clamped to 100).

pub const fn in_use() -> Self

A group with a pick inside it.

pub const fn dead() -> Self

A group no pick in which would leave anything.

pub const fn starting(self) -> Self

Marked as where to start.
