Struct daml_lf::PackageInfo

pub struct PackageInfo {
    pub package_id: String,
    pub package_name: String,
    pub version: Option<String>,
    pub language_version: LanguageVersion,
}

Information about a DamlPackage.

Fields

package_id: String

package_name: String

version: Option<String>

language_version: LanguageVersion

Implementations

impl PackageInfo

pub fn new(
    package_id: impl Into<String>,
    package_name: impl Into<String>,
    version: impl Into<Option<String>>,
    language_version: LanguageVersion
) -> Self

pub fn extract_from_dar(dar: &DarFile) -> DamlLfResult<Vec<Self>>

Extract extended information about the packages in a DarFile.

This is a relatively expensive operation as it involves creating a full DamlArchive representation of the given DarFile.

This is useful when examining a DarFile which has been constructed from a collection of packages (i.e. dalf files or packages downloaded from a ledger) which do not have metadata.

pub fn extract_from_archive(archive: &DamlArchive<'_>) -> Vec<Self>

Extract extended information about the packages in a DamlArchive.

pub fn extract_from_package(package: &DamlPackage<'_>) -> Self

Extract extended information from a DamlPackage.

pub fn find_from_archive<F>(archive: &DamlArchive<'_>, f: F) -> Option<Self> where
    F: Fn(&DamlPackage<'_>) -> bool, 

Extract extended package information about the package which matches the predicate.
