Struct ByteQty 

pub struct ByteQty(pub usize);

Quantity of memory used, measured in bytes.

Like usize but FromStr and Displays in a more friendly and less precise way

Parses from (with or without the internal space):

• <amount> (implicitly, bytes)
• <amount> B
• <amount> KiB/MiB/GiB/TiB (binary, 1024-based units)
• <amount> KB/MB/GB/TB (decimal, 1000-based units)

Displays to approximately 3 significant figures, preferring binary (1024-based) multipliers. (There is no facility for adjusting the format.)

Tuple Fields

0: usize

Implementations

impl ByteQty

pub const MAX: ByteQty

Maximum for the type

pub const fn as_usize(self) -> usize

Return the value as a plain number, a usize

Provided so call sites don’t need to write an opaque .0 everywhere, even though that would be fine.

Methods from Deref<Target = usize>

pub const MIN: usize = 0usize

pub const MAX: usize = 18_446_744_073_709_551_615usize

pub const BITS: u32 = 64u32

Trait Implementations

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ByteQty

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

Formats the value using the given formatter.

impl From<ByteQty> for usize

fn from(value: ByteQty) -> Self

Converts to this type from the input type.

impl From<usize> for ByteQty

fn from(value: usize) -> Self

Converts to this type from the input type.

impl FromStr for ByteQty

type Err = InvalidByteQty

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, IBQ>

Parses a string s to return a value of this type.

impl Hash for ByteQty

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 ByteQty

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

fn eq(&self, other: &ByteQty) -> 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 ByteQty

fn partial_cmp(&self, other: &ByteQty) -> 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.

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.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<f64> for ByteQty

type Error = InvalidByteQty

The type returned in the event of a conversion error.

fn try_from(f: f64) -> Result<ByteQty, IBQ>

Performs the conversion.

impl TryFrom<u64> for ByteQty

type Error = InvalidByteQty

The type returned in the event of a conversion error.

Performs the conversion.

impl Copy for ByteQty

impl Eq for ByteQty

impl StructuralPartialEq for ByteQty

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
