Struct Size 

pub struct Size { /* private fields */ }

Non-negative size in bytes. Constructors round fractional inputs up; negative or NaN inputs return Error::Argument.

Implementations

impl Size

pub fn from_bytes(b: f64) -> Result<Self, Error>

Build from a byte count (rounded up if fractional).

pub fn from_kilobytes(k: f64) -> Result<Self, Error>

Build from kilobytes (1 kB = 1000 B).

pub fn from_megabytes(m: f64) -> Result<Self, Error>

Build from megabytes.

pub fn from_gigabytes(g: f64) -> Result<Self, Error>

Build from gigabytes.

pub fn from_terabytes(t: f64) -> Result<Self, Error>

Build from terabytes.

pub fn parse(s: &str) -> Result<Self, Error>

Parse strings like "28MB", "1gb", "512 kb", "2megabytes". Case-insensitive, whitespace-tolerant. Accepts decimal values ("1.5gb") and concatenated parts (e.g. "1gb 256mb"). See FromStr.

pub const fn to_bytes(self) -> i64

Bytes (rounded up at construction).

pub fn to_kilobytes(self) -> f64

Fractional kilobytes.

pub fn to_megabytes(self) -> f64

Fractional megabytes.

pub fn to_gigabytes(self) -> f64

Fractional gigabytes.

pub fn to_terabytes(self) -> f64

Fractional terabytes.

Trait Implementations

impl Clone for Size

fn clone(&self) -> Size

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Size

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

Formats the value using the given formatter.

impl Default for Size

fn default() -> Size

Returns the “default value” for a type.

impl Display for Size

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

Auto-scaled human-readable rendering (e.g. "1.50 GB").

impl FromStr for Size

type Err = Error

The associated error which can be returned from parsing.

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

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

impl Hash for Size

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 Size

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

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

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