Expand description
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 makin your code both easier to refactor and more readable. Call try_build()
or try_build_or_recover()
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: &_) -> Result<public_field: _, Error_> |
pub_crate_field_builder | Use a function or closure: (private_field: &_) -> Result<pub_crate_field: _, Error_> |
Fields
private_field: Box<i32>
public_field_builder: PublicFieldBuilder_
pub_crate_field_builder: PubCrateFieldBuilder_
Implementations
Calls Visibility::try_new()
using the provided values. This is preferrable over calling try_new()
directly for the reasons listed above.
Calls Visibility::try_new_or_recover()
using the provided values. This is preferrable over calling try_new_or_recover()
directly for the reasons listed above.
