pub struct SectionSeparator { /* private fields */ }Expand description
Tracks whether any upgrade section has printed content yet, so a run covering several optional sections (shell presets, app configs, managed system configs) can emit exactly one blank-line separator between two sections that both printed something — never a leading separator before the first section, and never a stray blank line when a section had nothing to report.
Implementations§
Source§impl SectionSeparator
impl SectionSeparator
pub fn new() -> Self
Sourcepub fn with_preamble(preamble: impl Into<String>) -> Self
pub fn with_preamble(preamble: impl Into<String>) -> Self
Creates a separator that prints preamble immediately before its first
visible section. If no section begins, the preamble stays hidden.
Sourcepub fn begin(&mut self)
pub fn begin(&mut self)
Call immediately before printing a section’s header, only on the path where the section is actually about to print something.
pub fn has_printed(&self) -> bool
