Expand description

Responsible for rendering Kotlin code. Normally you need to just override [RenderKotlin::render].

Required Methods§

source

fn render_into(&self, block: &mut CodeBlock)

Renders Kotlin code into CodeBlock.

Usually it is good idea to avoid creating new CodeBlocks inside of this method implementation. Implementers should instead try to push their content into [block] parameter.

When you need to render another RenderKotlin object, use CodeBlock::push_renderable method. It will call RenderKotlin::render_into on the object and push its content into [block].

§Implementation example
use kotlin_poet_rs::io::RenderKotlin;
use kotlin_poet_rs::spec::{CodeBlock, Name};
use kotlin_poet_rs::tokens;

pub struct Argument {
    pub name: Option<Name>,
    pub value: CodeBlock,
}

impl RenderKotlin for Argument {
    fn render_into(&self, block: &mut CodeBlock) {
        if let Some(name) = &self.name {
            block.push_renderable(name);
            block.push_space();
            block.push_atom(tokens::ASSIGN);
            block.push_space();
        }
        block.push_atom(self.value.to_string().as_str());
    }
}

Provided Methods§

source

fn render_string(&self) -> String

Shortcut method for converting RenderKotlin::render_into output into String.
