Trait quote::ToTokens

pub trait ToTokens {
    fn to_tokens(&self, tokens: &mut Tokens);

    fn into_tokens(self) -> Tokens
    where
        Self: Sized,
    { ... }
}

Types that can be interpolated inside a quote! invocation.

Required Methods

fn to_tokens(&self, tokens: &mut Tokens)

Write self to the given Tokens.

Example implementation for a struct representing Rust paths like std::cmp::PartialEq:

extern crate quote;
use quote::{Tokens, ToTokens};

extern crate proc_macro2;
use proc_macro2::{TokenTree, TokenNode, Spacing, Span};

pub struct Path {
    pub global: bool,
    pub segments: Vec<PathSegment>,
}

impl ToTokens for Path {
    fn to_tokens(&self, tokens: &mut Tokens) {
        for (i, segment) in self.segments.iter().enumerate() {
            if i > 0 || self.global {
                // Double colon `::`
                tokens.append(TokenTree {
                    span: Span::def_site(),
                    kind: TokenNode::Op(':', Spacing::Joint),
                });
                tokens.append(TokenTree {
                    span: Span::def_site(),
                    kind: TokenNode::Op(':', Spacing::Alone),
                });
            }
            segment.to_tokens(tokens);
        }
    }
}

Provided Methods

fn into_tokens(self) -> Tokens where
    Self: Sized, 

Convert self directly into a Tokens object.

This method is implicitly implemented using to_tokens, and acts as a convenience method for consumers of the ToTokens trait.
