Struct Cost 

pub struct Cost(/* private fields */);

Repository cost value (0 or higher, higher = less preferred).

Default is 1000 when not explicitly set.

Examples

use dnf_repofile::Cost;

let c = Cost::try_new(500).unwrap();
assert_eq!(*c, 500);

Implementations

impl Cost

pub fn try_new(raw_value: i32) -> Result<Self, CostError>

impl Cost

pub fn into_inner(self) -> i32

Methods from Deref<Target = i32>

pub const MIN: i32

pub const MAX: i32

pub const BITS: u32 = u32::BITS

Trait Implementations

impl Clone for Cost

fn clone(&self) -> Cost

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cost

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

Formats the value using the given formatter.

impl Default for Cost

fn default() -> Self

Returns the “default value” for a type.

impl Deref for Cost

type Target = i32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for Cost

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

Formats the value using the given formatter.

impl Ord for Cost

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

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

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