Implementations

impl History

pub fn get(&self, bucket: &str) -> &[String]

pub fn push(&mut self, bucket: &'static str, entry: &str)

Remember an answer: newest first, no duplicates, 100 deep.

pub fn load(&mut self, path: &Path)

Load persisted history: bucket\tentry lines, newest first within each bucket, as History::save wrote them. Unknown buckets are dropped.

pub fn save(&self, path: &Path, cap: usize)

Write the history back, at most cap entries per bucket, the buckets in a fixed order. The file is replaced whole and kept private: it holds addresses and searches.
