`try_map` and `flip` methods for `Option`. These allow more ergonomic error handling when mapping functions that return `Result` over `Option`.
Adds a try_map method to arrays.
A macro like try!, but turns a Result into an Option, mainly for use in a filter_map
Maps enum variants to numbers and viceversa
A derive macro for converting a HashMap<String, String> into a struct
Derive macro to auto-generate From<Source> for Target by mapping struct fields — zero boilerplate struct conversion
Procedural macro implementation for struct-mapper — do not depend on this directly, use struct-mapper instead
Range calculation helper.
Extends iterators with `try_all` to convert iterator of results into result of iterator of okays
An attribute proc macro to convert structs with named fields of the same generic type into a single-array-field tuple struct with array-index-based accessor and mutator methods.
Explicit concrete Error type to manage errors that end a process/program
Utilities for fallible mapping over `Option` and iterators using functions that can return `Result`s.
