There are two `trait` in crate `unhtml`
- `FromHtml`
The only method of `FromHtml` you should care about is `fn from_html(html: &str) -> Result` and this method is implemented for all types implemented `FromStr`
```rust
impl FromHtml for T
where E: failure::Fail,
T: FromStr {
fn from_html(html: &str) -> Result {
Ok(T::from_str(html.trim())?)
}
}
```
You can implement `FromHtml` automatically for `struct` by crate `unhtml_derive`
[](https://crates.io/crates/unhtml_derive)
- `VecFromHtml`
`VecFromHtml` is implemented for `Vec where T: FromHtml` by default
```rust
impl VecFromHtml for Vec
where T: FromHtml {
type Elem = T;
}
```
As `FromHtml` is implemented for `u8` by default
```rust
use unhtml::scraper::Html;
use unhtml::VecFromHtml;
let html = Html::parse_fragment(r#"
Title
"#);
let results = Vec::::from_attr("#test > a", "href", html.root_element()).unwrap();
assert_eq!(1u8, results[0]);
assert_eq!(2u8, results[1]);
assert_eq!(3u8, results[2]);
```
