Struct ElementWriter

pub struct ElementWriter<'a, W> { /* private fields */ }

A struct to write an element. Contains methods to add attributes and inner elements to the element

Implementations

impl<'a, W> ElementWriter<'a, W>

pub fn with_attribute<'b, I>(self, attr: I) -> Self

where I: Into<Attribute<'b>>,

Adds an attribute to this element.

pub fn with_attributes<'b, I>(self, attributes: I) -> Self

where I: IntoIterator, I::Item: Into<Attribute<'b>>,

Add additional attributes to this element using an iterator.

The yielded items must be convertible to Attribute using Into.

pub fn new_line(self) -> Self

Push a new line inside an element between attributes. Note, that this method does nothing if Writer was created without indentation support.

Examples

The following code

let mut buffer = Vec::new();
let mut writer = Writer::new_with_indent(&mut buffer, b' ', 2);
writer
  .create_element("element")
    //.new_line() (1)
    .with_attribute(("first", "1"))
    .with_attribute(("second", "2"))
    .new_line()
    .with_attributes([
        ("third", "3"),
        ("fourth", "4"),
    ])
    //.new_line() (2)
    .write_empty();

will produce the following XMLs:

<!-- result of the code above. Spaces always is used -->
<element first="1" second="2"
         third="3" fourth="4"/>

<!-- if uncomment only (1) - indent depends on indentation
     settings - 2 spaces here -->
<element
  first="1" second="2"
  third="3" fourth="4"/>

<!-- if uncomment only (2). Spaces always is used  -->
<element first="1" second="2"
         third="3" fourth="4"
/>

impl<'a, W: Write> ElementWriter<'a, W>

pub fn write_text_content( self, text: BytesText<'_>, ) -> Result<&'a mut Writer<W>>

Write some text inside the current element.

pub fn write_cdata_content( self, text: BytesCData<'_>, ) -> Result<&'a mut Writer<W>>

Write a CData event <![CDATA[...]]> inside the current element.

pub fn write_pi_content(self, pi: BytesPI<'_>) -> Result<&'a mut Writer<W>>

Write a processing instruction <?...?> inside the current element.

pub fn write_empty(self) -> Result<&'a mut Writer<W>>

Write an empty (self-closing) tag.

pub fn write_inner_content<F>(self, closure: F) -> Result<&'a mut Writer<W>>

where F: FnOnce(&mut Writer<W>) -> Result<()>,

Create a new scope for writing XML inside the current element.
