Rust macro to automatically generates setter methods for a struct's fields. This can be used to add setters to a plain data struct, or to help in implementing builders.
For a related library that creates separate builder types, see
rust-derive-builder.
```rust use derive_setters::*;
struct BasicStruct { #[setters(rename = "test")] a: u32, b: u32, c: u32, }
assert_eq!( BasicStruct::default().test(30).b(10).c(20), BasicStruct { a: 30, b: 10, c: 20 }, ); ```
The following options can be set on the entire struct.
#[setters(generate = false)] causes setter methods to not be generated by default.#[setters(generate_private = false)] causes setter methods to not be generated by default for private fields.#[setters(generate_public = false)] causes setter methods to not be generated by default for public fields.#[setters(no_std)] causes the generated code to use core instead of std.#[setters(prefix = "with_")] causes the setter method on all fields to be prefixed with the given string.#[setters(generate_delegates(ty = "OtherTy", field = "some_field"))] causes all setter methods on this struct to
be duplicated on the target struct, instead modifying self.some_field instead of self.#[setters(generate_delegates(ty = "OtherTy", method = "get_field"))] does the same thing as above, except calling
get_field with no arguments instead of directly accessing a field.The following options can be set on a fields.
#[setters(generate)] causes a setter method to be generated, overriding struct-level settings.#[setters(skip)] causes no setter method to be generated.#[setters(rename = "setter_name")] causes the setter method to have a different name from the field.
This overwrites add_prefix.The following options can be set on either the entire struct, or on an individual field. You
can disable the features for a particular field with #[setters(option = false)]
#[setters(into)] causes the setter method to accept any type that can be converted into the field's type
via Into.#[setters(strip_option)] causes the setter method to accept T instead of Option<T>. If applied to a field
that isn't wrapped in an Option, it does nothing.#[setters(bool)] causes the setter method to take no arguments, and set the field to true.#[setters(borrow_self)] causes the generated setter method to borrow &mut self instead of taking self. This
is better for code styles that require mutable setters rather than immutable setters.This project is licensed under either of
