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],

}

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.

deprecation_notes: &'a DeprecationNotes

Emit deprecation notes to the user.

bindings: Bindings

Bindings to libstd or libcore.
