Struct nitro_fs::fat::FileAllocTable

pub struct FileAllocTable { /* fields omitted */ }

Wrapper for handling File Allocation Table stuff

Implementations

impl FileAllocTable

pub fn new(fat: &[u8]) -> Result<Self, Error>

Takes a raw FAT and reads it into a list.

Errors

Will return an error if the length of the data is not divisible by 8. This is because each FAT entry is two 32-bit integers.

It will also return an error if reading from the data fails.

pub fn get(&self, id: u16) -> Option<AllocInfo>

Returns the allocation info for the given file ID.

If the given ID is not in the list, it will return None.

Trait Implementations

impl Clone for FileAllocTable

fn clone(&self) -> FileAllocTable

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileAllocTable

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for FileAllocTable

fn default() -> FileAllocTable

Returns the "default value" for a type.

impl Eq for FileAllocTable

impl Hash for FileAllocTable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

impl Ord for FileAllocTable

fn cmp(&self, other: &FileAllocTable) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<FileAllocTable> for FileAllocTable

fn eq(&self, other: &FileAllocTable) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &FileAllocTable) -> bool

This method tests for !=.

impl PartialOrd<FileAllocTable> for FileAllocTable

fn partial_cmp(&self, other: &FileAllocTable) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &FileAllocTable) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &FileAllocTable) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &FileAllocTable) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &FileAllocTable) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
