Rust Define Result at Declan Brian blog

Rust Define Result. A specialized result type for i/o operations. It is used for functions that can return an error. Returns the provided default (if err), or applies a function to the contained value (if ok). [−] pub type result = result <t, error>; The result type in rust is an enum defined in the standard library. See the std::result module documentation for details. Helpers for dealing with nested result and option types. We've seen that the option enum can be used as a return value from functions that may fail, where none can be returned to indicate failure. Convert a option<<strong>result</strong><t, e>> to result<option<t>, e> and vice versa. This type is broadly used across std::io for any. Arguments passed to map_or are eagerly. Result is similar to option, but indicates the success or failure of an operation, each with a different enum variant. Result is a type that represents either success (ok) or failure (err).
