Trait used to generate HTML from Rust structures
It contains the following optional definitions:
// Defaults to an empty string
fn tag(&self) -> Cow<'static, str> { /* ... */ }
// Defaults to empty vec
fn attributes(&self) -> Vec<Attribute> { /* ... */ }
// Defaults to empty vec
fn inner_html(&self) -> Vec<Box<dyn Htmlify>> { /* ... */ }
The following method should not need to be implemented:
// Calls `as_raw_html` for each of the items returned by `inner_html`
fn inner_html_as_string(&self) -> String { /* ... */ }
The following definition also should not need to be implemented, but may on occasion be useful to override:
fn as_raw_html(&self) -> String
{
format!
(
"<{0} {2}> {1} </{0}>",
self.tag(),
self.inner_html_as_string(),
self.attributes()
.iter()
.map(Attribute::to_string)
.collect::<Vec<String>>()
.join(" ")
)
}
The web-sys
feature may be enabled to allow access to the following default function:
fn as_element(&self) -> Option<web_sys::Element> { /* ... */ }
The yew
feature may be enabled to allow access to the following default function:
fn as_yew_node(&self) -> Html { /* ... */ }
There are 3 other tools included in this crate:
- An
Htmlify
implementation for&str
. This is a special case which simply returns the string itself whenas_raw_html
is called, and returnsNone
whenas_element
is called. This is so text-content "leaves" can be represented. (and the default implementation ofas_element
understands this). - An
Attribute
struct to store key-value pairs as strings, used specifically for element attributes. These useCow<'static, str>
to leave optimization details up to the implementor. - The
web-sys
feature also provides access to anappend_to_document_body
function which takes anyimpl Htmlify
and attempts to append it to the document body (through web_sys calls). This is here purely for convenience.
