Struct Metrics 

#[non_exhaustive]
pub struct Metrics {
    pub char_width: f32,
    pub line_height: f32,
}

Bundled font metrics for one call to Backend::measure — the two numbers (Backend::char_width and Backend::line_height) every primitive’s *Measure type is actually built from. A primitive’s XMeasure::from_metrics(&Metrics) constructor (see crate::TextInputMeasure::from_metrics for the pattern) turns it into that primitive’s own measure shape without the app touching char_width / line_height by name.

#[non_exhaustive]: this is in-tree-only today (no external Backend implementors construct it — only Backend::measure’s default body does), but consumers (coord-tui, vimcode) do read the two public fields, so a later field addition should stay source-compatible with field-access call sites instead of becoming a silent breaking change.

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.

char_width: f32

Same value Backend::char_width returns.

line_height: f32

Same value Backend::line_height returns.
