Struct derive_builder_core::Setter

pub struct Setter<'a> {
    pub enabled: bool,
    pub try_setter: bool,
    pub visibility: Visibility,
    pub pattern: BuilderPattern,
    pub attrs: &'a [Attribute],
    pub ident: Ident,

}

Setter for the struct fields in the build method, implementing quote::ToTokens.

Examples

Will expand to something like the following (depending on settings):

pub fn foo(&mut self, value: Foo) -> &mut Self {
    let mut new = self;
    new.foo = ::std::option::Option::Some(value);
    new
}

Fields

enabled: bool

Enables code generation for this setter fn.

try_setter: bool

Enables code generation for the try_ variant of this setter fn.

visibility: Visibility

Visibility of the setter, e.g. syn::Visibility::Public.

pattern: BuilderPattern

How the setter method takes and returns self (e.g. mutably).

attrs: &'a [Attribute]

Attributes which will be attached to this setter fn.

ident: Ident

Name of this setter fn.

field_ident: &'a Ident

Name of the target field.

field_type: &'a Type

Type of the target field.

The corresonding builder field will be Option<field_type>.

generic_into: bool

Make the setter generic over Into<T>, where T is the field type.

strip_option: bool

Make the setter remove the Option wrapper from the setter, remove the need to call Some(...). when combined with into, the into is used on the content Type of the Option.

deprecation_notes: &'a DeprecationNotes

Emit deprecation notes to the user.

bindings: Bindings

Bindings to libstd or libcore.

Trait Implementations
