Struct GutterMarks 

pub struct GutterMarks {
    pub severity: Option<Severity>,
    pub breakpoint: bool,
}

Everything the gutter has to say about ONE line.

Why this is a struct and not a second Option<Severity> parameter

The gutter had exactly one mark cell and gutter_cells took exactly one Option<Severity>. A breakpoint is not a severity — it is a thing the OPERATOR put there, not a thing a producer found — so squeezing it into that cell would mean a line carrying both an error and a breakpoint could only show one of them, and whichever lost would be invisible with no indication that anything had been hidden.

So each plane gets its own cell, and they arrive together in one value. There is deliberately no From<Option<Severity>> and no Default: every construction names both planes, which is what makes adding a third (git hunks are next) a compile error at every call site rather than a silently-omitted column.

Fields

severity: Option<Severity>

The WORST finding severity on the line, or None.

breakpoint: bool

Whether a debug breakpoint sits on the line.

Implementations

impl GutterMarks

pub const fn new(severity: Option<Severity>, breakpoint: bool) -> Self

Both planes, named.

pub const fn clear() -> Self

Nothing on this line. Spelled out rather than Default so a caller that means “I have not looked yet” cannot spell it the same way.
