Struct ouroboros_examples::VisibilityBuilder

pub struct VisibilityBuilder<PublicFieldBuilder_: for<'this> FnOnce(&'this <Box<i32> as Deref>::Target) -> &'this i32, PubCrateFieldBuilder_: for<'this> FnOnce(&'this <Box<i32> as Deref>::Target) -> &'this i32> {
    pub private_field: Box<i32>,
    pub public_field_builder: PublicFieldBuilder_,
    pub pub_crate_field_builder: PubCrateFieldBuilder_,
}

A more verbose but stable way to construct self-referencing structs. It is comparable to using StructName { field1: value1, field2: value2 } rather than StructName::new(value1, value2). This has the dual benefit of making your code both easier to refactor and more readable. Call build() to construct the actual struct. The fields of this struct should be used as follows:

Field	Suggested Use
private_field	Directly pass in the value this field should contain
public_field_builder	Use a function or closure: (private_field: &_) -> public_field: _
pub_crate_field_builder	Use a function or closure: (private_field: &_) -> pub_crate_field: _

Fields

private_field: Box<i32>

public_field_builder: PublicFieldBuilder_

pub_crate_field_builder: PubCrateFieldBuilder_

Implementations

impl<PublicFieldBuilder_: for<'this> FnOnce(&'this <Box<i32> as Deref>::Target) -> &'this i32, PubCrateFieldBuilder_: for<'this> FnOnce(&'this <Box<i32> as Deref>::Target) -> &'this i32> VisibilityBuilder<PublicFieldBuilder_, PubCrateFieldBuilder_>

pub fn build(self) -> Visibility

Calls Visibility::new() using the provided values. This is preferrable over calling new() directly for the reasons listed above.
