[−][src]Macro genco::prelude::quote_in
quote_in!() { /* proc-macro */ }
Behaves the same as quote! while quoting into an existing token stream
with <target> => <quoted>
.
This macro takes a destination stream followed by an =>
and the tokens to
extend that stream with.
Note that the <target>
arguments must be borrowable. So a mutable
reference like &mut rust::Tokens
will have to be dereferenced when used
with this macro.
let mut tokens = rust::Tokens::new(); quote_in!(tokens => hello world); fn generate_into(tokens: &mut rust::Tokens) { quote_in! { *tokens => hello... world! }; }
Example
use genco::prelude::*; let mut tokens = rust::Tokens::new(); quote_in! { tokens => fn foo() -> u32 { 42 } }
Example use inside of quote!
[quote_in!] can be used inside of a quote! macro by using a scope.
use genco::prelude::*; let tokens: rust::Tokens = quote! { fn foo(v: bool) -> u32 { #(ref out { quote_in! { *out => if v { 1 } else { 0 } } }) } };
