Implementations

impl PackageManager

pub fn detect() -> Result<Self>

Detects the package manager by reading /etc/os-release.

Errors

• InvalidData if the /etc/os-release does not contain an ID= and ID_LIKE entry.
• InvalidInput if the discovered ID is not in the supported list.
• Other io::Error variants propagated from fs::read_to_string.

Examples found in repository

examples/api_check.rs (line 6)

fn main() -> io::Result<()> {
    let pm = PackageManager::detect()?;
    let name = pm.name();
    let count = pm.package_count()?;
    println!("{count} ({name})");
    Ok(())
}

pub const fn name(&self) -> &'static str

Returns the package manager command name.

Examples found in repository

examples/api_check.rs (line 7)

fn main() -> io::Result<()> {
    let pm = PackageManager::detect()?;
    let name = pm.name();
    let count = pm.package_count()?;
    println!("{count} ({name})");
    Ok(())
}

pub fn package_count(&self) -> Result<u64>

Returns the installed package count for the manager.

Errors

Returns an error if the command fails, output is invalid UTF-8, output is empty, or the count cannot be parsed as an integer.

Examples found in repository

examples/api_check.rs (line 8)

fn main() -> io::Result<()> {
    let pm = PackageManager::detect()?;
    let name = pm.name();
    let count = pm.package_count()?;
    println!("{count} ({name})");
    Ok(())
}

Trait Implementations

impl Clone for PackageManager

fn clone(&self) -> PackageManager

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackageManager

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

Formats the value using the given formatter.

impl PartialEq for PackageManager

fn eq(&self, other: &PackageManager) -> 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.
