Struct cargo::core::compiler::custom_build::BuildScriptOutputs
source · pub struct BuildScriptOutputs {
outputs: HashMap<Metadata, BuildOutput>,
}
Expand description
Map of packages to build script output.
This initially starts out as empty. Overridden build scripts get
inserted during build_map
. The rest of the entries are added
immediately after each build script runs.
The Metadata
is the unique metadata hash for the RunCustomBuild Unit of
the package. It needs a unique key, since the build script can be run
multiple times with different profiles or features. We can’t embed a
Unit
because this structure needs to be shareable between threads.

Implementations§
source§impl BuildScriptOutputs
impl BuildScriptOutputs
sourcefn insert(
&mut self,
pkg_id: PackageId,
metadata: Metadata,
parsed_output: BuildOutput
)
fn insert( &mut self, pkg_id: PackageId, metadata: Metadata, parsed_output: BuildOutput )
Inserts a new entry into the map.
sourcefn contains_key(&self, metadata: Metadata) -> bool
fn contains_key(&self, metadata: Metadata) -> bool
Returns true
if the given key already exists.
sourcepub fn get(&self, meta: Metadata) -> Option<&BuildOutput>
pub fn get(&self, meta: Metadata) -> Option<&BuildOutput>
Gets the build output for the given key.
sourcepub fn iter(&self) -> impl Iterator<Item = (&Metadata, &BuildOutput)>
pub fn iter(&self) -> impl Iterator<Item = (&Metadata, &BuildOutput)>
Returns an iterator over all entries.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
