Struct guppy::CargoMetadata

source ·
pub struct CargoMetadata(/* private fields */);
Expand description

Deserialized Cargo metadata.

Returned by a MetadataCommand or constructed from cargo metadata JSON output.

This is an alternative entry point for constructing a PackageGraph, to be used if the JSON output of cargo metadata is already available. To construct a PackageGraph from an on-disk Cargo workspace, use MetadataCommand.

This struct implements serde::Serialize and Deserialize.
