iter

Helpers for any Iterator, not only slices: work on a lazy, single-use or unbounded source.

Install

Cargo feature iter (enabled by default). To compile only this module:

cargo add helpers4 --no-default-features --features iter

or in Cargo.toml:

[dependencies]
helpers4 = { version = "0.0.5", default-features = false, features = ["iter"] }

Import path: helpers4::iter.
