Struct PackageInput 

pub struct PackageInput {
    build_info: BuildInfo,
    package_info: PackageInfo,
    mtree: Mtree,
    mtree_digest: Sha256Checksum,
    input_dir: InputDir,
    scriptlet: Option<PathBuf>,
    relative_paths: Vec<PathBuf>,
}

A package input directory.

An input directory must contain

• a valid ALPM-MTREE file,
• a valid BUILDINFO file,
• a valid PKGINFO file,

Further, the input directory may contain an alpm-install-scriptlet file and zero or more package data files (see alpm-package).

Fields

build_info: BuildInfo

package_info: PackageInfo

mtree: Mtree

mtree_digest: Sha256Checksum

input_dir: InputDir

scriptlet: Option<PathBuf>

relative_paths: Vec<PathBuf>

Implementations

impl PackageInput

pub fn input_dir(&self) -> &Path

Returns the input directory of the PackageInput as Path reference.

pub fn build_info(&self) -> &BuildInfo

Returns a reference to the BuildInfo data of the PackageInput.

Note

The BuildInfo data relates directly to an on-disk file tracked by the PackageInput. This method provides access to the data as present during the creation of the PackageInput. While the data can be guaranteed to be correct, the on-disk file may have changed between creation of the PackageInput and the call of this method.

pub fn package_info(&self) -> &PackageInfo

Returns a reference to the PackageInfo data of the PackageInput.

Note

The PackageInfo data relates directly to an on-disk file tracked by the PackageInput. This method provides access to the data as present during the creation of the PackageInput. While the data can be guaranteed to be correct, the on-disk file may have changed between creation of the PackageInput and the call of this method.

pub fn mtree(&self) -> Result<&Mtree, Error>

Returns a reference to the Mtree data of the PackageInput.

Compares the stored hash digest of the file with that of the file on disk.

Errors

Returns an error if

• the file on disk can no longer be read,
• or the file on disk has a changed hash digest.

pub fn install_scriptlet(&self) -> Option<&Path>

Returns the optional alpm-install-scriptlet of the PackageInput as Path reference.

Note

The alpm-install-scriptlet path relates directly to an on-disk file tracked by the PackageInput. This method provides access to the data as present during the creation of the PackageInput. While the data can be guaranteed to be correct, the on-disk file may have changed between creation of the PackageInput and the call of this method.

pub fn relative_paths(&self) -> &[PathBuf]

Returns all paths relative to the PackageInput’s input directory.

pub fn input_paths(&self) -> Result<InputPaths<'_, '_>, Error>

Returns an InputPaths for the input directory and all relative paths contained in it.

Trait Implementations

impl Clone for PackageInput

fn clone(&self) -> PackageInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackageInput

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

Formats the value using the given formatter.

impl TryFrom<InputDir> for PackageInput

fn try_from(value: InputDir) -> Result<Self, Self::Error>

Creates a PackageInput from input directory path.

This function reads ALPM-MTREE, BUILDINFO and PKGINFO files in path, collects the path of an existing alpm-install-scriptlet and validates them. All data files below path are then checked against the ALPM-MTREE data.

Errors

Returns an error if

• value is not a valid InputDir,
• there is no valid BUILDINFO file,
• there is no valid ALPM-MTREE file,
• there is no valid PKGINFO file,
• or one of the files below dir does not match the ALPM-MTREE data.

type Error = Error

The type returned in the event of a conversion error.
