Struct HotUpdateDecision 

pub struct HotUpdateDecision {
    pub can_hot: bool,
    pub indexed_blocker: Option<String>,
    pub page_free_space: usize,
}

Verdict + diagnostics.

Fields

can_hot: bool

True when the caller may take the HOT path.

indexed_blocker: Option<String>

When can_hot is false and an indexed column blocked the decision, its name. None means either HOT passed or the page-fit check failed.

page_free_space: usize

Echoes the input so the caller can log the numeric margin.

impl PartialEq for HotUpdateDecision

fn eq(&self, other: &HotUpdateDecision) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
