}Expand description
This trait deals with tagged HTML &str data.
Provided Associated Constants§
Sourceconst TAG_DOCTYPE_PAT: &'static str = "<!doctype"
const TAG_DOCTYPE_PAT: &'static str = "<!doctype"
Lowercase pattern to check if this is a Doctype tag.
Sourceconst TAG_DOCTYPE_HTML_PAT: &'static str = "<!doctype html"
const TAG_DOCTYPE_HTML_PAT: &'static str = "<!doctype html"
Lowercase pattern to check if this Doctype is HTML.
Sourceconst TAG_DOCTYPE_HTML: &'static str = "<!DOCTYPE html>"
const TAG_DOCTYPE_HTML: &'static str = "<!DOCTYPE html>"
Doctype HTML tag. This is inserted by
<HtmlString>.prepend_html_start_tag()
Sourceconst START_TAG_HTML_PAT: &'static str = "<html"
const START_TAG_HTML_PAT: &'static str = "<html"
Pattern to check if f this is an HTML start tag.
Sourceconst END_TAG_HTML: &'static str = "</html>"
const END_TAG_HTML: &'static str = "</html>"
HTML end tag.
Required Methods§
Sourcefn is_empty_html(&self) -> bool
fn is_empty_html(&self) -> bool
We consider self empty, when it equals to <!DOCTYPE html...> or
when it is empty.
Sourcefn has_html_start_tag(&self) -> bool
fn has_html_start_tag(&self) -> bool
True if stream starts with <!DOCTYPE html...>.
Sourcefn is_html_unchecked(&self) -> bool
fn is_html_unchecked(&self) -> bool
Some heuristics to guess if the input stream contains HTML. Current implementation: True if:
- The stream starts with
<!DOCTYPE html ...>, or - the stream starts with
<html ...>
This function does not check if the recognized HTML is valid.
Provided Methods§
Sourcefn is_empty_html2(html: &str) -> bool
fn is_empty_html2(html: &str) -> bool
We consider html empty, when it equals to <!DOCTYPE html...> or
when it is empty.
This is identical to is_empty_html(), but does not pull in
additional trait bounds.
Sourcefn has_html_start_tag2(html: &str) -> bool
fn has_html_start_tag2(html: &str) -> bool
True if html starts with <!DOCTYPE html...>.
This is identical to has_html_start_tag(), but does not pull in
additional trait bounds.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
