Struct bloguen::ops::TagName

pub struct TagName(_);

A verified-valid post tag.

Methods

impl TagName

pub fn load_additional_post_tags(
    post_root: &(String, PathBuf)
) -> Result<Vec<TagName>, Error>

Read additional post tags from the specified root directory.

If the tags file doesn't exist, an empty vector returned.

Examples

Given $POST_ROOT/tags containing:

vodka	depression

коммунизм

The following holds:

let post_root: PathBuf = /* obtained elsewhere */;
let tag_names =
    TagName::load_additional_post_tags(&("$POST_ROOT/".to_string(), post_root)).unwrap();
assert_eq!(tag_names,
           vec!["vodka".parse().unwrap(), "depression".parse().unwrap(), "коммунизм".parse().unwrap()]);
