Struct debian_control::relations::Relation

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

Implementations

impl Relation

pub fn new( name: &str, version_constraint: Option<(VersionConstraint, Version)>, ) -> Self

pub fn simple(name: &str) -> Self

Create a new simple relation, without any version constraints.

Example

use debian_control::relations::Relation;
let relation = Relation::simple("samba");
assert_eq!(relation.to_string(), "samba");

pub fn drop_constraint(&mut self) -> bool

Remove the version constraint from the relation.

Example

use debian_control::relations::{Relation, VersionConstraint};
let mut relation = Relation::new("samba", Some((VersionConstraint::GreaterThanEqual, "2.0".parse().unwrap())));
relation.drop_constraint();
assert_eq!(relation.to_string(), "samba");

pub fn name(&self) -> String

Return the name of the package in the relation.

Example

use debian_control::relations::Relation;
let relation = Relation::simple("samba");
assert_eq!(relation.name(), "samba");

pub fn archqual(&self) -> Option<String>

Return the archqual

Example

use debian_control::relations::Relation;
let relation: Relation = "samba:any".parse().unwrap();
assert_eq!(relation.archqual(), Some("any".to_string()));

pub fn set_archqual(&mut self, archqual: &str)

Set the architecture qualifier for this relation.

Example

use debian_control::relations::Relation;
let mut relation = Relation::simple("samba");
relation.set_archqual("any");
assert_eq!(relation.to_string(), "samba:any");

pub fn version(&self) -> Option<(VersionConstraint, Version)>

Return the version constraint and the version it is constrained to.

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

Return an iterator over the architectures for this relation

pub fn profiles(&self) -> impl Iterator<Item = Vec<BuildProfile>> + '_

Returns an iterator over the build profiles for this relation

Trait Implementations

impl Debug for Relation

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

Formats the value using the given formatter.

impl Display for Relation

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

Formats the value using the given formatter.

impl From<Relation> for Entry

fn from(relation: Relation) -> Self

Converts to this type from the input type.

impl FromStr for Relation

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 PartialEq for Relation

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.
