[`concat_idents!`]: https://doc.rust-lang.org/std/macro.concat_idents.html This crate provides a flexible way to paste together identifiers in a macro, including using pasted identifiers to define new items. ```toml [dependencies] paste = "1.0" ``` This approach works with any Rust compiler 1.31+.
## Pasting identifiers Within the `paste!` macro, identifiers inside `[<`...`>]` are pasted together to form a single identifier. ```rust use paste::paste; paste! { // Defines a const called `QRST`. const []: &str = "success!"; } fn main() { assert_eq!( paste! { [].len() }, 8, ); } ```
## More elaborate example The next example shows a macro that generates accessor methods for some struct fields. It demonstrates how you might find it useful to bundle a paste invocation inside of a macro\_rules macro. ```rust use paste::paste; macro_rules! make_a_struct_and_getters { ($name:ident { $($field:ident),* }) => { // Define a struct. This expands to: // // pub struct S { // a: String, // b: String, // c: String, // } pub struct $name { $( $field: String, )* } // Build an impl block with getters. This expands to: // // impl S { // pub fn get_a(&self) -> &str { &self.a } // pub fn get_b(&self) -> &str { &self.b } // pub fn get_c(&self) -> &str { &self.c } // } paste! { impl $name { $( pub fn [](&self) -> &str { &self.$field } )* } } } } make_a_struct_and_getters!(S { a, b, c }); fn call_some_getters(s: &S) -> bool { s.get_a() == s.get_b() && s.get_c().is_empty() } ```
## Case conversion Use `$var:lower` or `$var:upper` in the segment list to convert an interpolated segment to lower- or uppercase as part of the paste. For example, `[]` would paste to `ld_bc_expr` if invoked with $reg=`Bc`. Use `$var:snake` to convert CamelCase input to snake\_case. Use `$var:camel` to convert snake\_case to CamelCase. These compose, so for example `$var:snake:upper` would give you SCREAMING\_CASE. The precise Unicode conversions are as defined by [`str::to_lowercase`] and [`str::to_uppercase`]. [`str::to_lowercase`]: https://doc.rust-lang.org/std/primitive.str.html#method.to_lowercase [`str::to_uppercase`]: https://doc.rust-lang.org/std/primitive.str.html#method.to_uppercase
## Pasting documentation strings Within the `paste!` macro, arguments to a #\[doc ...\] attribute are implicitly concatenated together to form a coherent documentation string. ```rust use paste::paste; macro_rules! method_new { ($ret:ident) => { paste! { #[doc = "Create a new `" $ret "` object."] pub fn new() -> $ret { todo!() } } }; } pub struct Paste {} method_new!(Paste); // expands to #[doc = "Create a new `Paste` object"] ```
