    pub enum Fail {
        ArgumentMissing(String),

🔬 This is a nightly-only experimental API. (`rustc_private`)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via `Cargo.toml` instead?

The type returned when the command line does not conform to the expected format. Use the `Debug` implementation to output detailed information.

## Variants

`ArgumentMissing(String)`

A required option is not present.

`OptionDuplicated(String)`
🔬 This is a nightly-only experimental API. (`rustc_private`)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via `Cargo.toml` instead?

A single occurrence option is being used multiple times.

`UnexpectedArgument(String)`
🔬 This is a nightly-only experimental API. (`rustc_private`)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via `Cargo.toml` instead?

There's an argument being passed to a non-argument option.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
