Struct rsvg::xml::attributes::Attributes
source · pub struct Attributes {
attrs: Box<[(QualName, DefaultAtom)]>,
id_idx: Option<u16>,
class_idx: Option<u16>,
}
Expand description
Iterable wrapper for libxml2’s representation of attribute/value.
See the new_from_xml2_attributes
function for information.
Fields§
§attrs: Box<[(QualName, DefaultAtom)]>
§id_idx: Option<u16>
§class_idx: Option<u16>
Implementations§
source§impl Attributes
impl Attributes
sourcepub unsafe fn new_from_xml2_attributes(
n_attributes: usize,
attrs: *const *const c_char
) -> Result<Attributes, LoadingError>
pub unsafe fn new_from_xml2_attributes( n_attributes: usize, attrs: *const *const c_char ) -> Result<Attributes, LoadingError>
Creates an iterable Attributes
from the C array of borrowed C strings.
With libxml2’s SAX parser, the caller’s startElementNsSAX2Func
callback gets passed a xmlChar **
for attributes, which
comes in groups of (localname/prefix/URI/value_start/value_end).
In those, localname/prefix/URI are NUL-terminated strings;
value_start and value_end point to the start-inclusive and
end-exclusive bytes in the attribute’s value.
Safety
This function is unsafe because the caller must guarantee the following:
-
attrs
is a valid pointer, with (n_attributes * 5) elements. -
All strings are valid UTF-8.
sourcepub fn iter(&self) -> AttributesIter<'_> ⓘ
pub fn iter(&self) -> AttributesIter<'_> ⓘ
Creates an iterator that yields (QualName, &'a str)
tuples.
