Enum RowRun 

pub enum RowRun {
    Source {
        len: u32,
        style: Style,
    },
    Inlay {
        len: u32,
    },
}

One coloured run within a display row’s combined text.

Perf plan A.2. Carries either a lattice_syntax::Style tag for source bytes or an Inlay discriminant for inlay-spliced bytes. Runs are NOT baked to RGB — renderers map style → Rgba at paint time against the resolved theme table. Reasons for the tag, not the colour:

• A theme switch doesn’t invalidate the producer’s cache (only the colour resolution at paint changes; the run topology doesn’t).
• The producer stays theme-independent — no theme reads.

Slice A.2b.2 promoted this from a struct to an enum so the producer can mark inlay-text bytes distinctly. Consumers map Inlay to their inlay-virtual-text colour without having to track byte ranges separately.

display-line B-series: this is the DisplayLine run type, owned by the cells / DisplayMatrix substrate. (The deleted RowPrepaint was the original consumer; B4.2 removed it but display_matrix.rs keeps RowRun as its style-run type.)

Variants

Source

Source-text run carrying a tree-sitter style tag.

Fields

len: u32

Number of utf-8 bytes in this run inside the combined text.

style: Style

Style tag from the highlight grammar. Style::Default for runs that fall outside any tree-sitter capture.

Inlay

Inlay-virtual-text run. Carries only the byte length; the colour is consumer-resolved.

Fields

len: u32

Number of utf-8 bytes of inlay text in this run.

Implementations

impl RowRun

pub fn len(&self) -> u32

Byte length of this run inside the row’s combined text. Convenience accessor so consumers don’t need to match every time the partition is walked. (Clippy: paired enums often also expose is_empty, but RowRun::Inlay { len: 0 } would be a producer bug — the partition is built with the invariant that every run is non-empty, so an is_empty would be misleading.)
