Struct debian_control::lossless::relations::Entry

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

Implementations

impl Entry

pub fn new() -> Self

pub fn wrap_and_sort(&self) -> Self

pub fn relations(&self) -> impl Iterator<Item = Relation> + '_

pub fn get_relation(&self, idx: usize) -> Option<Relation>

pub fn satisfied_by( &self, package_version: &mut dyn FnMut(&str) -> Option<Version>, ) -> bool

Check if this entry is satisfied by the given package versions.

Arguments

• package_version - A function that returns the version of a package.

Example

use debian_control::lossless::relations::Entry;
let entry = Entry::from(vec!["samba (>= 2.0)".parse().unwrap()]);
assert!(entry.satisfied_by(&mut |name| {
   match name {
   "samba" => Some("2.0".parse().unwrap()),
   _ => None
}}));

pub fn remove(&mut self)

Remove this entry

Trait Implementations

impl Debug for Entry

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

Formats the value using the given formatter.

impl Default for Entry

fn default() -> Self

Returns the “default value” for a type.

impl Display for Entry

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

Formats the value using the given formatter.

impl From<Entry> for Relations

fn from(entry: Entry) -> Self

Converts to this type from the input type.

impl From<Relation> for Entry

fn from(relation: Relation) -> Self

Converts to this type from the input type.

impl From<Vec<Relation>> for Entry

fn from(relations: Vec<Relation>) -> Self

Converts to this type from the input type.

impl FromStr for Entry

type Err = String

The associated error which can be returned from parsing.

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

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

impl Ord for Entry

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Entry

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

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