Trait convey::Render

pub trait Render {
    fn render_for_humans(&self, fmt: &mut Formatter) -> Result<(), Error>;
    fn render_json(&self, fmt: &mut Formatter) -> Result<(), Error>;
}

Implement this for your own components

Required Methods

fn render_for_humans(&self, fmt: &mut Formatter) -> Result<(), Error>

How to render your type for humans

fn render_json(&self, fmt: &mut Formatter) -> Result<(), Error>

How to render your type to JSON

If your type implements Serialize, this can easily just be fmt.write(self). Alternatively, you might want to use something like serde_json’s json! macro.

Implementations on Foreign Types

impl<'a, T> Render for &'a Twhere
    T: Render,

Render automatically works with references

Examples

let mut out = convey::new().add_target(test_target.target())?;
out.print(text("owned element"))?;
out.print(&text("reference to an element"))?;

fn render_for_humans(&self, fmt: &mut Formatter) -> Result<(), Error>

fn render_json(&self, fmt: &mut Formatter) -> Result<(), Error>

impl<'a> Render for &'a str

Render a string slice

Examples

let mut out = convey::new().add_target(test_target.target())?;
out.print("Hello, World!")?;

fn render_for_humans(&self, fmt: &mut Formatter) -> Result<(), Error>

fn render_json(&self, fmt: &mut Formatter) -> Result<(), Error>

impl<'a> Render for String

Render a string

Examples

let mut out = convey::new().add_target(test_target.target())?;
out.print(String::from("Hello, World!"))?;

fn render_for_humans(&self, fmt: &mut Formatter) -> Result<(), Error>

fn render_json(&self, fmt: &mut Formatter) -> Result<(), Error>
