ReloadReason

Enum ReloadReason 

Source
#[non_exhaustive]
pub enum ReloadReason { Initial, FileChanged(PathBuf), RemoteChanged, Manual, Recovered, }
Expand description

What caused a snapshot to be installed.

Recorded at the call site that installs, because nothing downstream can reconstruct it: by the time a hook runs, a file change and a manual reload() have produced the identical swap.

#[non_exhaustive]: the set of things that can install a configuration grows with the crate, and matching on it must keep compiling when it does.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Initial

A Builder::init — the call that establishes a configuration, whether or not one was already installed.

§

FileChanged(PathBuf)

A watched file changed. Carries the path whose event opened the reload’s debounce window.

One path, not the set: the debounce collapses a flurry into a single reload, and the window that a ..data symlink swap or a two-file edit produces genuinely covers several. The path names what triggered this reload, which is the question a log line asks; the keys that actually moved are changed_paths’ job.

§

RemoteChanged

A remote store pushed a document through RemoteSink::apply.

§

Manual

The program installed it: reload, a generated replace, ConfigCell::store, or a ReloadGroup commit.

§

Recovered

The last-known-good cache, after the sources refused to load at init.

Implementations§

Source§

impl ReloadReason

Source

pub fn as_str(&self) -> &'static str

A short, stable label — the category, without the path.

For a metric dimension or a structured log field, where FileChanged’s path is unbounded cardinality and the category is not.

use yansi::{Paint, Color};

painted.fg(Color::White);

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
