TryIterator
Implements the TryIterator trait, which will add the following fallible methods to Iterator:
| New method | Analog to |
|---|---|
try_all |
all |
try_any |
any |
try_position |
position |
try_rposition |
rposition |
Motivation
This crate was born out of necessity of a fallible version for the Iterator::position method, which was asked in this StackOverflow question. Contrary to the equivalent try_for_each, the solution is rather cumbersome, which resulted in this issue in the Rust repository.
Until the standard library adds these fallible methods – if ever –, they are available in this crate.
Usage
Add the dependency in your Cargo.toml:
[dependencies]
try-iterator = { version = "1.0.0" }
Then import the prelude at the top of your source files:
use try_iterator::prelude::*;
The new methods will be automatically present in Iterator.
