Struct Fatfs 

pub struct Fatfs<T> { /* private fields */ }

Represents a FAT filesystem.

Implementations

impl<T> Fatfs<T>

pub fn new_sdcard<H>(drive: u8, sd_card_driver: T) -> Result<Self, EspError>

where T: BorrowMut<SdCardDriver<H>>,

Create a new FAT filesystem instance for a given SD card driver.

Arguments

• Drive number to assign to the filesystem.
• SD card driver instance.

pub fn drive(&self) -> u8

Get the drive number of the filesystem.

pub fn format( &mut self, configuration: &FormatConfiguration, buf: &mut [u8], ) -> Result<(), EspError>

Format the partition with the given configuration.

Arguments

• Formatting configuration.
• Buffer to use when formatting.

pub fn mount(&mut self) -> Result<MountedFatfs<'_, T>, EspError>

Mount the filesystem and return a handle to it.

impl Fatfs<()>

pub unsafe fn new_raw_part( drive: u8, partition: *const esp_partition_t, ) -> Result<Self, EspError>

Create a new - readonly - FAT filesystem instance for a given raw partition in the internal flash. This API is unsafe because currently esp-idf-hal does not have a safe way to represent a flash partition - neither a raw one, nor a wear-leveling one.

Arguments

• Drive number to assign to the filesystem.
• Raw partition pointer.

Safety

While the filesystem object is alive, the partition should not be modified elsewhere

pub unsafe fn new_wl_part( drive: u8, partition: wl_handle_t, ) -> Result<Self, EspError>

Create a new FAT filesystem instance for a given raw partition in the internal flash. This API is unsafe because currently esp-idf-hal does not have a safe way to represent a flash partition - neither a raw one, nor a wear-leveling one.

Arguments

• Drive number to assign to the filesystem.
• A handle to a wear-leveling partition.

Safety

While the filesystem object is alive, the partition should not be modified elsewhere

Trait Implementations

impl<T> Drop for Fatfs<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
