# Description
As part of the refactor to split spans off of Value, this moves to using
helper functions to create values, and using `.span()` instead of
matching span out of Value directly.
Hoping to get a few more helping hands to finish this, as there are a
lot of commands to update :)

# Description
This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.
We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

# Description
- A new one is the removal of unnecessary `#` in raw strings without `"`
inside.
-
https://rust-lang.github.io/rust-clippy/master/index.html#/needless_raw_string_hashes
- The automatically applied removal of `.into_iter()` touched several
places where #9648 will change to the use of the record API. If
necessary I can remove them @IanManske to avoid churn with this PR.
- Manually applied `.try_fold` in two places
- Removed a dead `if`
- Manual: Combat rightward-drift with early return
I noticed that `open some_big_file | into binary` cannot be cancelled
with `ctrl+c`.
This small PR fixes that by checking `ctrl+c` in
`RawStream::into_bytes()`, and does the same in
`RawStream::into_string()` for good measure.
# Description
_(Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.)_
I implemented the status bar we talk about yesterday. The idea was
inspired by the progress bar of `wget`.
I decided to go for the second suggestion by `@Reilly`
> 2. add an Option<usize> or whatever to RawStream (and ListStream?) for
situations where you do know the length ahead of time
For now only works with the command `save` but after the approve of this
PR we can see how we can implement it on commands like `cp` and `mv`
When using `fetch` nushell will check if there is any `content-length`
attribute in the request header. If so, then `fetch` will send it
through the new `Option` variable in the `RawStream` to the `save`.
If we know the total size we show the progress bar
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.
Please let me know If I need to make any changes and I will be happy to
do it.
# User-Facing Changes
A new flag (`--progress` `-p`) was added to the `save` command
Examples:
```nu
fetch https://github.com/torvalds/linux/archive/refs/heads/master.zip | save --progress -f main.zip
fetch https://releases.ubuntu.com/22.04.1/ubuntu-22.04.1-desktop-amd64.iso | save --progress -f main.zip
open main.zip --raw | save --progress main.copy
```

I am getting some errors and its weird because the errors are showing up
in files i haven't touch. Is this normal?

I've been working on streaming and pipeline interruption lately. It was
bothering me that checking ctrl+c (something we want to do often) always
requires a bunch of boilerplate like:
```rust
use std::sync::atomic::Ordering;
if let Some(ctrlc) = &engine_state.ctrlc {
if ctrlc.load(Ordering::SeqCst) {
...
```
I added a helper method to cut that down to:
```rust
if nu_utils::ctrl_c::was_pressed(&engine_state.ctrlc) {
...
```
Fixes#7246 and #1898.
Darren noticed that `open /dev/random` could not be interrupted by
`ctrl+c`. Thankfully the solution was very simple; it looks like we just
forgot to check `ctrlc` in the `impl Iterator for RawStream`!
To reproduce this, just run `open /dev/random` and then cancel it with
`ctrl+c`.
This adds new pipeline connectors called out> and err> which redirect either stdout or stderr to a file. You can also use out+err> (or err+out>) to redirect both streams into a file.
