Struct uefi::proto::media::file::FileSystemInfo

source · [−]

#[repr(C)]
pub struct FileSystemInfo { /* private fields */ }

Expand description

System volume information

May only be obtained on the root directory’s file handle.

Please note that only the system volume’s volume label may be set using this information structure. Consider using FileSystemVolumeLabel instead.

Implementations

source

impl FileSystemInfo

source

pub fn new<'buf>(
    storage: &'buf mut [u8],
    read_only: bool,
    volume_size: u64,
    free_space: u64,
    block_size: u32,
    volume_label: &CStr16
) -> Result<&'buf mut Self, FileInfoCreationError>

Create a FileSystemInfo structure

The structure will be created in-place within the provided storage buffer. The buffer must be large enough to hold the data structure, including a null-terminated UCS-2 name string.

The buffer must be correctly aligned. You can query the required alignment using the alignment() method of the Align trait that this struct implements.

source

pub fn read_only(&self) -> bool

Truth that the volume only supports read access

source

pub fn volume_size(&self) -> u64

Number of bytes managed by the file system

source

pub fn free_space(&self) -> u64

Number of available bytes for use by the file system

source

pub fn block_size(&self) -> u32

Nominal block size by which files are typically grown

source

pub fn volume_label(&self) -> &CStr16

Volume label

Trait Implementations

source

impl Align for FileSystemInfo

source

fn alignment() -> usize

Required memory alignment for this type

source

fn offset_up_to_alignment(val: usize) -> usize

Calculate the offset from val necessary to make it aligned, rounding up. For example, if val is 1 and the alignment is 8, this will return 7. Returns 0 if val == 0. Read more
