pub struct FileWrite { /* private fields */ }

A safe wrapper over a C filestream with write permissions

Implementations

impl FileWrite

pub fn create(path: &str) -> Result<FileWrite, PROSErr>

Creates a new file

Errors

• Returns PROSErr::IO on low-level hardware I/O error
• Returns PROSErr::Invalid when the length or path is invalid
• Returns PROSErr::NoEntry when the path cannot be found
• Returns PROSErr::Access when access is denied
• Returns PROSErr::Exists when access is denied
• Returns PROSErr::ReadOnlyFS when the SD card is write protected
• Returns PROSErr::NXIO when the drive number is invalid or not an FAT32 drive
• Returns PROSErr::NoBuffSpace when the drive has no work area
• Returns PROSErr::NoMoreFiles when there are too many open files

Warning

All paths must start with /usd/, if you don’t it won’t work

pub fn open(path: &str) -> Result<FileWrite, PROSErr>

Opens a file that already exists

Errors

• Returns PROSErr::IO on low-level hardware I/O error

pub fn write(&mut self, string: &str) -> Result<(), PROSErr>

Writes a string to the file

WARNING

Errors

Trait Implementations

impl Drop for FileWrite

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.
