sql: Remove `From` impl for `Yaml` idea comment

2022-03-21T01:13:57+00:00

This was obviated by using `Cow::Borrowed` and `Cow::Owned` directly
when creating a `Yaml`.

main: Write YAML to standard output

2022-03-19T19:41:31+00:00

Create an adapter from `std::fmt::Write` to `std::io::Write` based on
the following idea in the standard library:

https://github.com/rust-lang/rust/blob/master/library/std/src/io/mod.rs#L1634-L1652

Since `yaml_rust::YamlEmitter::new()` requires a `std::fmt::Write`,
adapt standard output so the emitter can write to it.

select(): Build a `yaml_rust::yaml::Hash` for each row

2022-03-18T23:37:32+00:00

Instead of my earlier `std::collections::HashMap`, build the type we
want to return directly in the row closure.

Required copying some data like the column names, but I don't see a way
around that. I suppose we could make `yaml_rust::Yaml`s from the column
headers in the row closure too instead of copying an existing column
header that we otherwise never use.

This nearly passes the test I have for this function, but it includes
the `id` column in the `Yaml` hash. The primary key column will need to
be removed.

select(): Trying to inspect data queried from database

2022-03-17T23:49:56+00:00

Can't get the info from inside the closure it seems. The row iterator
doesn't seem to be looping. Not sure what the story is yet. Maybe I'm
not converting the data types correctly.

yaml::sql::Yaml: Make this type `pub(crate)`

2022-03-17T23:05:48+00:00

It doesn't need to be completely public.

Yaml: Wrap a `Cow<'_, yaml_rust::Yaml>` instead of `yaml_rust::Yaml`

2022-03-17T22:57:09+00:00

This allows us to use a borrowed `yaml_rust::Yaml` for `ToSql` and an
owned `yaml_rust::Yaml` for `FromSql`.
