This is meant to be much easier to discover than the current approach of directly invoking `Executor` methods.
In addition, I'm improving documentation for the `query*()` functions across the board.
* query_as: don't stop stream after decoding error
Fixes https://github.com/launchbadge/sqlx/issues/1884
When a single row cannot be converted to the target type of query_as,
it should not prevent the library user from accessing the other rows
Otherwise, the user cannot access all query results in query_as.
* use union in tests to maximize db compatibility
- Remove Type bound from Encode + Decode which removes the defaults
for produces() and accepts(). This allows custom type implementations
to be more flexible.
* removes the lifetime from Row
* removes MySqlQueryAs, SqliteQueryAs, etc. (no longer needed)
* introduce query_scalar
* introduce Decode::accepts to allow overriding runtime type checking
per-type (replaces TypeInfo::compatible)
* introduce Encode::produces to allow overriding the encoded type per-value
* adds a lifetime to Arguments (and introduce the HRTB HasArguments)
to support zero-copy encoding with SQLite
* renames Database::RawBuffer to HasArguments::ArgumentBuffer
* introduce Connect::connect_with to provide an ConnectOptions type
explicitly to opt-out of connection string parsing
* introduce Value and ValueRef traits to allow decoding-deferred
extraction of values from Rows
* introduce Encode::encode_by_ref and change Encode::encode to take
by-value to try and re-use memory where possible
* use thiserror to generate sqlx::Error
* [!] temporarily removes query logging
* [!] temporarily removes transactions
Prints each query performed at DEBUG level,
along with a timing of how long the query took
to execute.
Slow queries will be printed at WARN level.
Currently the slow query threshold is
hardcoded to 1 second.
* tweak FromRow to accept Row by reference, should make it easier to compose FromRow impls
* rename ColumnIndex::resolve to ColumnIndex::index
* document behaviors
