Struct Command

pub struct Command { /* private fields */ }

Used to invoke the telety-generated macro in a manageable way.

Implementations

impl Command

pub fn apply( &'static self, macro_path: Path, needle: impl Into<SingleToken>, haystack: impl ToTokens, ) -> Apply

Creates a macro invocation to use this command with the telety-generated macro at macro_path.
The output of the command will be inserted into haystack at each instance of needle. macro_path must point to a valid telety-generated macro, otherwise a compile error will occur.
To support future Commands, args are passed to the command invocation, but they are not currently used.

Example

#[proc_macro]
pub fn my_public_macro(tokens: TokenStream) -> TokenStream {
    // ...
    let my_needle: TokenTree = format_ident!("__my_needle__").into();
    v1::UNIQUE_IDENT.apply(
        &parse_quote!(crate::MyTeletyObj),
        &my_needle,
        quote! {
            my_crate::my_macro_implementation!(#my_needle);
        },
        None,
    )
}
#[doc(hidden)]
#[proc_macro]
pub fn my_macro_implementation(tokens: TokenStream) -> TokenStream {
    let ident: Ident = parse2(tokens);
    // ...
}
