No such file bug on rust-lang/rust

[pickfire]

Describe the bug

It errors but the error should be incorrect.

To Reproduce
Steps to reproduce the behaviour:

1. git clone https://github.com/rust-lang/rust
2. cd rust
3. cargo spellcheck
4. Error: Failed to parse manifest file /home/ivan/src/pickfire/rs/rust/src/bootstrap/Cargo.toml: No such file or directory (os error 2)
5. File actually does exists, ls does show the file. Content:

[package]
authors = ["The Rust Project Developers"]
name = "bootstrap"
version = "0.0.0"
edition = "2018"

[lib]
name = "bootstrap"
path = "lib.rs"
doctest = false

[[bin]]

version = "0.3"
features = ["fileapi", "ioapiset", "jobapi2", "handleapi", "winioctl"]

[dev-dependencies]

It is quite long but it also does not work for other directories as well.

Expected behavior

I don't know, it should check something.

The error message is misleading that cargo_toml yields, after reading first to a str it becomes more obvious:

[2020-07-24T15:20:25Z TRACE cargo_spellcheck::traverse] Handling manifest member src/tools/rust-installer -> /media/supersonic1t/projects/rust/src/tools/rust-installer
[src/traverse/mod.rs:148] &manifest_file = "/snip/projects/rust/src/tools/rust-installer/Cargo.toml"
Error: No such file or directory (os error 2)

Cargo.toml
19:  "src/tools/rust-installer",

is actually not containing a Cargo.toml

I guess it's better to just warn the user about this and continue rather then aborting.

PR #76 covers changes needed for this, but running it on the rust codebase also uncovered a few more issues which will be addressed in the same PR

[drahnr]

Please give 0.3.0-beta.1 a shot & feel free to re-open if this particular issue persists.

Looks like it works in one of my crate based on standard library liballoc. But there is an issue in rust-lang/rust:

> cargo spellcheck
thread 'main' panicked at 'byte index 40 is not a char boundary; it is inside '♫' (bytes 38..41) of `///         println!("♫ Still alive ♫");`', /home/ivan/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/libcore/str/mod.rs:1920:47
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

[drahnr]

Could you open a new issue with backtrack?

Funny enough, I tested it yesterday on last week's rust codebase which seemed fine (no further steps done, just git clone)
