Crate embedded_sdmmc

embedded-sdmmc-rs - A SD/MMC Library written in Embedded Rust

Structs

Attributes	Indicates whether a directory entry is read-only, a directory, a volume label, etc.
Block	Represents a standard 512 byte block (also known as a sector). IBM PC formatted 5.25" and 3.5" floppy disks, SD/MMC cards up to 1 GiB in size and IDE/SATA Hard Drives up to about 2 TiB all have 512 byte blocks.
BlockCount	Represents the a number of blocks (or sectors). Add this to a BlockIdx to get an actual address on disk.
BlockIdx	Represents the linear numeric address of a block (or sector). The first block on a disk gets BlockIdx(0) (which usually contains the Master Boot Record).
Cluster	Represents a cluster on disk.
Controller	A Controller wraps a block device and gives access to the volumes within it.
DirEntry	Represents a directory entry, which tells you about other files and directories.
Directory	Represents an open directory on disk.
Fat16Volume	Identifies a FAT16 Volume on the disk.
Fat32Volume	Identifies a FAT32 Volume on the disk.
File	Represents an open file on disk.
SdMmcSpi	Represents an SD Card interface built from an SPI peripheral and a Chip Select pin. We need Chip Select to be separate so we can clock out some bytes without Chip Select asserted (which puts the card into SPI mode).
ShortFileName	An MS-DOS 8.3 filename. 7-bit ASCII only. All lower-case is converted to upper-case by default.
Timestamp	Represents an instant in time, in the local time zone. TODO: Consider replacing this with POSIX time as a u32, which would save two bytes at the expense of some maths.
Volume	Represents a partition with a filesystem within it.
VolumeIdx	A VolumeIdx is a number which identifies a volume (or partition) on a disk. VolumeIdx(0) is the first primary partition on an MBR partitioned disk.

Enums

Error	Represents all the ways the functions in this crate can fail.
FilenameError	Various filename related errors that can occur.
Mode	The different ways we can open a file.
SdMmcError	The possible errors SdMmcSpi can generate.
VolumeType	This enum holds the data for the various different types of filesystems we support.

Constants

MAX_OPEN_DIRS	We have to track what directories are open to prevent users from modifying open directories (like creating a file when we have an open iterator).
MAX_OPEN_FILES	We have to track what files and directories are open to prevent users from deleting open files (like Windows does).

Traits

BlockDevice	Represents a block device - a device which can read and write blocks (or sectors). Only supports devices which are <= 2 TiB in size.
TimeSource	Things that impl this can tell you the current time.
