Add a block cache

2

It would improve performance if we had a write-through block cache, particularly in the cluster allocation loop or for multiple small writes (as we'd avoid the repeated reads). The user...

LFN support

3

Was: > The LFN code assumes the code points are all valid UTF-16 and not surrogate pairs exist. This may not be a valid assumption. We should do a proper...

This PR begins to separate the transport from the SD protocol, so we can use other interfaces such as SDIO. Before I went any further, I thought I'd better check...

Make Directory::iterate_dir version returning an Iterator

3

In the current implementation, [Directory::iterate_dir](https://docs.rs/embedded-sdmmc/latest/embedded_sdmmc/struct.Directory.html#method.iterate_dir) accepts a callback to be executed for each entry. Returning an Iterator instead could make working with it much easier: 1. It would match [std::fs::read_dir](https://doc.rust-lang.org/std/fs/fn.read_dir.html)...

Ensuring generic device-level reset

2

I've run into a road-block trying to make my use of the library generic across different implementations of `BlockDevice`. The issue is that with the `SdCard` type, I am able...

should use SpiBus, not SpiDevice

How to do multi-block writes?

10

I feel like I am missing something here, but are multi-block writes not possible through the public API? `SdCardInner::write(..)` seems to have the support for writing multiple blocks properly, but...

Support different codepages

1

Currently we assume that short file names contain valid UTF-8, which is not always true. We should have some kind of generic type param for a codepage convertor which can...

Explore interior mutability

2

Now that `critical-section` is a thing, maybe we can consider interior mutability: * `Volume` can hold an `&VolumeManager` * `Directory` and `File` can hold an `&Volume` ```rust let volume =...
