pub enum DependencyStatus {
    Installed {
        version: String,
    },
    ToInstall,
    ToUpgrade {
        current: String,
        required: String,
    },
    Conflict {
        reason: String,
    },
    Missing,
}

Status of a dependency relative to the current system state.

This enum represents the installation status and requirements for a dependency, used throughout the dependency resolution process to track what actions are needed.

Variants

Installed

Already installed and version matches requirement.

Fields

version: String

Installed version of the package.

ToInstall

Not installed, needs to be installed.

ToUpgrade

Installed but outdated, needs upgrade.

Fields

current: String

Current installed version.

required: String

Required version for upgrade.

Conflict

Conflicts with existing packages.

Fields

reason: String

Reason for the conflict.

Missing

Cannot be found in configured repositories or AUR.

Implementations

impl DependencyStatus

pub const fn is_installed(&self) -> bool

What: Check if the dependency is already installed.

Inputs:

• self: The dependency status to check.

Output:

• Returns true if the dependency is installed (regardless of version).

Details:

• Returns true for both Installed and ToUpgrade variants.

pub const fn needs_action(&self) -> bool

What: Check if the dependency needs action (install or upgrade).

Inputs:

• self: The dependency status to check.

Output:

• Returns true if the dependency needs to be installed or upgraded.

Details:

• Returns true for ToInstall and ToUpgrade variants.

pub const fn is_conflict(&self) -> bool

What: Check if there’s a conflict with this dependency.

Inputs:

• self: The dependency status to check.

Output:

• Returns true if the dependency has a conflict.

Details:

• Returns true only for the Conflict variant.

pub const fn priority(&self) -> u8

What: Get a priority value for sorting (lower = more urgent).

Inputs:

• self: The dependency status to get priority for.

Output:

• Returns a numeric priority where lower numbers indicate higher urgency.

Details:

• Priority order: Conflict (0) < Missing (1) < ToInstall (2) < ToUpgrade (3) < Installed (4).

Trait Implementations

impl Clone for DependencyStatus

fn clone(&self) -> DependencyStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DependencyStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DependencyStatus

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DependencyStatus

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

Formats the value using the given formatter.

impl PartialEq for DependencyStatus

fn eq(&self, other: &DependencyStatus) -> 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 Serialize for DependencyStatus

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DependencyStatus
