Struct ext4_view::DirEntryName

pub struct DirEntryName<'a>(/* private fields */);

Name of a DirEntry, stored as a reference.

This is guaranteed at construction to be a valid directory entry name.

Implementations

impl<'a> DirEntryName<'a>

pub const MAX_LEN: usize = 255usize

Maximum length of a DirEntryName.

pub fn as_str(&self) -> Result<&'a str, Utf8Error>

Convert to a &str if the name is valid UTF-8.

pub fn display(&self) -> BytesDisplay<'_>

Get an object that implements Display to allow conveniently printing names that may or may not be valid UTF-8. Non-UTF-8 characters will be replaced with ‘�’.

Trait Implementations

impl<'a> AsRef<[u8]> for DirEntryName<'a>

fn as_ref(&self) -> &'a [u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Clone for DirEntryName<'a>

fn clone(&self) -> DirEntryName<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for DirEntryName<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for DirEntryName<'a>

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for DirEntryName<'a>

fn cmp(&self, other: &DirEntryName<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a, T> PartialEq<T> for DirEntryName<'a>

where T: AsRef<[u8]>,

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd for DirEntryName<'a>

fn partial_cmp(&self, other: &DirEntryName<'a>) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl<'a> TryFrom<&'a [u8]> for DirEntryName<'a>

type Error = DirEntryNameError

The type returned in the event of a conversion error.

fn try_from(bytes: &'a [u8]) -> Result<Self, DirEntryNameError>

Performs the conversion.

impl<'a, const N: usize> TryFrom<&'a [u8; N]> for DirEntryName<'a>

type Error = DirEntryNameError

The type returned in the event of a conversion error.

fn try_from(bytes: &'a [u8; N]) -> Result<Self, DirEntryNameError>

Performs the conversion.

impl<'a> TryFrom<&'a str> for DirEntryName<'a>

type Error = DirEntryNameError

The type returned in the event of a conversion error.

fn try_from(s: &'a str) -> Result<Self, DirEntryNameError>

Performs the conversion.
