Implementations

impl Unit

pub fn name(&self) -> &str

The unit name.

pub fn symbol(&self) -> &str

The unit symbol.

pub fn convert_to(&self, scalar: f64, to: &Unit) -> Result<f64, String>

Convert the unit to the new scalar.

Arguments

• scalar The new scalar value.
• to The new unit to convert too.

Returns

The new scalar value.

pub fn is_byte_unit(&self) -> bool

Returns true if the unit is for bytes.

Returns

True if the unit is for bytes.

Trait Implementations

impl Debug for Unit

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

Formats the value using the given formatter.

impl Default for Unit

fn default() -> Unit

Returns the “default value” for a type.

impl Display for Unit

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

Formats the value using the given formatter.

impl Div<&'static Unit> for &Unit

Division operator

type Output = Result<&'static Unit, String>

The resulting type after applying the / operator.

fn div(self, other: &'static Unit) -> Self::Output

Performs the / operation.

impl From<&str> for &Unit

Make a Haystack Unit from a &str slice If no unit is found, the default empty unit is returned

fn from(value: &str) -> Self

Converts to this type from the input type.

impl Hash for Unit

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,

Feeds a slice of this type into the given Hasher.

impl Mul<&'static Unit> for &Unit

Multiplication operator

type Output = Result<&'static Unit, String>

The resulting type after applying the * operator.

fn mul(self, other: &'static Unit) -> Self::Output

Performs the * operation.

impl PartialEq<Unit> for Unit

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

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

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

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

impl PartialOrd<Unit> for Unit

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

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

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

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

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

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

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

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

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

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