Rust result docs

pub const fn into_ok_or_err (self) -> T. 🔬 This is a nightly-only experimental API. ( result_into_ok_or_err #82223) Returns the Ok value if self is Ok, and the Err value if self is Err. In other words, this function returns the value (the T) of a Result<T, T>, regardless of whether or not that result is Ok or Err. API documentation for the Rust `Result` enum in crate `std`. ... Applies the "?" operator. A return of Ok(t) means that the execution should continue normally, and the result of ? is the value t. A return of Err(e) means that execution should branch to the innermost enclosing catch, or return from the function.Aug 05, 2020 · The inherently strict nature of Rust often results in passable "reference" or "encyclopedia" level documentation. This is great and really elevates the minimum documentation quality, as compared with other languages. Rust programs implement the heap directly by defining a custom global_allocator. Programs may implement their own global_allocator based on its specific needs. Refer to the custom heap example for more information.

In other words, this function returns the value (the T) of a Result<T, T>, regardless of whether or not that result is Ok or Err. 虽然通常的 Rust 风格是直接导入类型,但 Result 的别名通常不是,以便更容易区分它们。 Result 通常被假定为 std::result::Result ,因此这个别名的用户通常会使用 io::Result 而不是隐藏prelude对 std::result::Result 的导入。 Examples 将 io::Result 冒泡给调用Ok has Result as superclass. Ok(123) is Result == true Result < T > Abstract class. Represent common type Result, which may be a Ok or Err. Don't instantiate it. Use implementations: Ok() and Err() instead.

For example, if the data type of the valid output is u64 and error type is String, return type should be Result<u64, String>.See full list on learning-rust.github.io Returns the contained Err value, but never panics.. Unlike unwrap_err, this method is known to never panic on the result types it is implemented for.Therefore, it can be used instead of unwrap_err as a maintainability safeguard that will fail to compile if the ok type of the Result is later changed to a type that can actually occur.

While usual Rust style is to import types directly, aliases of Result often are not, to make it easier to distinguish between them. Result is generally assumed to be std::result::Result, and so users of this alias will generally use io::Result instead of shadowing the prelude's import of std::result::Result.

A Result can be iterated over. This can be helpful if you need an iterator that is conditionally empty. The iterator will either produce a single value (when the Result is Ok), or produce no values (when the Result is Err). For example, into_iter acts like once(v) if the Result is Ok(v), and like empty() if the Result is Err.
