Trait tagger::WriteAttr

pub trait WriteAttr: Write + Sized {
    fn polyline_data<F>(&mut self, func: F) -> Result<&mut Self, Error>
    where
        F: FnOnce(&'x mut PolyLineBuilder<'y, Self>) -> Result<&'x mut PolyLineBuilder<'y, Self>, Error>,
    { ... }
    fn path_data<F>(&mut self, func: F) -> Result<&mut Self, Error>
    where
        F: FnOnce(&'x mut PathBuilder<'y, Self>) -> Result<&'x mut PathBuilder<'y, Self>, Error>,
    { ... }
    fn with_attr(
        &mut self, 
        s: &str, 
        func: impl FnOnce(&mut Self) -> Result
    ) -> Result<&mut Self, Error> { ... }
    fn attr(&mut self, s: &str, val: impl Display) -> Result<&mut Self, Error> { ... }
}

Functions the user can call to add attributes. AttributeWriter could have implemented these, but lets use a trait to simplify lifetimes.

Provided methods

fn polyline_data<F>(&mut self, func: F) -> Result<&mut Self, Error> where
    F: FnOnce(&'x mut PolyLineBuilder<'y, Self>) -> Result<&'x mut PolyLineBuilder<'y, Self>, Error>, 

Write the data attribute for a svg polyline.

fn path_data<F>(&mut self, func: F) -> Result<&mut Self, Error> where
    F: FnOnce(&'x mut PathBuilder<'y, Self>) -> Result<&'x mut PathBuilder<'y, Self>, Error>, 

Write the data attribute for a svg path.

fn with_attr(
    &mut self,
    s: &str,
    func: impl FnOnce(&mut Self) -> Result
) -> Result<&mut Self, Error>

Write an attribute where the user can write the value part using wr macro or the write macro

fn attr(&mut self, s: &str, val: impl Display) -> Result<&mut Self, Error>

Write an attribute with the specified tag and value using the values fmt::Display trait.
