[−][src]Struct ouroboros_examples::ChainHackTryBuilder
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 |
---|---|
a | Directly pass in the value this field should contain |
b_builder | Use a function or closure: (a: &_) -> Result<b: _, Error_> |
c_builder | Use a function or closure: (b: &_) -> Result<c: _, Error_> |
Fields
a: Box<i32>
b_builder: BBuilder_
c_builder: CBuilder_
Implementations
impl<BBuilder_: for<'this> FnOnce(&'this i32) -> Result<Box<&'this i32>, Error_>, CBuilder_: for<'this> FnOnce(&'this &'this i32) -> Result<Box<&'this i32>, Error_>, Error_> ChainHackTryBuilder<BBuilder_, CBuilder_, Error_>
[src]
pub fn try_build(self) -> Result<ChainHack, Error_>
[src]
Calls ChainHack::try_new()
using the provided values. This is preferrable over calling try_new()
directly for the reasons listed above.
pub fn try_build_or_recover(self) -> Result<ChainHack, (Error_, Heads)>
[src]
Calls ChainHack::try_new_or_recover()
using the provided values. This is preferrable over calling try_new_or_recover()
directly for the reasons listed above.
