Implementations

impl FSExtentType

pub const Data: Self

An extent type to indicate valid data.

Use this type for all extents on a file system that doesn’t support sparse files.

Tip: The kernel keeps track of the end of file, so it knows a range of [EOF, allocated space] is uninitialized. Because of this behavior, it’s valid to pass the data extent type for such a range.

pub const ZeroFill: Self

An extent type to indicate uninitialized data.

Only use this extent type in file systems that support sparse files, and only then to represent ranges in the file that aren’t allocated yet.

Trait Implementations

impl Clone for FSExtentType

fn clone(&self) -> FSExtentType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FSExtentType

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

Formats the value using the given formatter.

impl Encode for FSExtentType

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for FSExtentType

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 Ord for FSExtentType

fn cmp(&self, other: &FSExtentType) -> 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,

Restrict a value to a certain interval.

impl PartialEq for FSExtentType

fn eq(&self, other: &FSExtentType) -> 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 PartialOrd for FSExtentType

fn partial_cmp(&self, other: &FSExtentType) -> 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 RefEncode for FSExtentType

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.
