This library is used for anonymously escaping code inside Rust code and avoiding repeating my_language!(code) everywhere. This is a tool for people implementing procedural macros and trying to integrate their language into Rust. It uses an escape mechanism (the # symbol) to specify we enter the user-language world.
Example with the pcp EDSL (truncated and modified for clarity):
pcp! {
// ...
for _ in 0..n {
let n: i32 = n as i32;
queens.push(#(variables <- 0..n));
}
for i in 0..n-1 {
for j in i + 1..n {
let a = i as i32;
let b = j as i32;
#{
constraints <- queens[i] + a != queens[j] + b;
constraints <- queens[i] - a != queens[j] - b;
}
}
}
// ...
}
Traditional Rust code is in the macro pcp! but we easily escape our user-defined language with #(code) or #{code} depending on the nature of the generated code (expression or statements). Control will be given to the user-compiler (parameter of the main function compile_anonymous_macro) for the code inside # and the generated Rust code will be automatically inserted.
