Trait quote::ToTokens[−][src]

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

    fn to_token_stream(&self) -> TokenStream { ... }
    fn into_token_stream(self) -> TokenStream
    where
        Self: Sized,
    { ... }
}

Types that can be interpolated inside a quote! invocation.

Required methods

`fn to_tokens(&self, tokens: &mut TokenStream)`[src]

Write self to the given TokenStream.

The token append methods provided by the TokenStreamExt extension trait may be useful for implementing ToTokens.

Example

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

use proc_macro2::{TokenTree, Spacing, Span, Punct, TokenStream};
use quote::{TokenStreamExt, ToTokens};

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

impl ToTokens for Path {
    fn to_tokens(&self, tokens: &mut TokenStream) {
        for (i, segment) in self.segments.iter().enumerate() {
            if i > 0 || self.global {
                // Double colon `::`
                tokens.append(Punct::new(':', Spacing::Joint));
                tokens.append(Punct::new(':', Spacing::Alone));
            }
            segment.to_tokens(tokens);
        }
    }
}

Provided methods

`fn to_token_stream(&self) -> TokenStream`[src]

Convert self directly into a TokenStream object.

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

`fn into_token_stream(self) -> TokenStream where Self: Sized,` [src]

Convert self directly into a TokenStream object.

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