Struct ToolchainSummary 

pub struct ToolchainSummary {
    pub tools: BTreeMap<String, String>,
    pub sources: BTreeMap<String, String>,
    pub compiler_wrapper: Option<CompilerWrapperSummary>,
}

Lightweight, non-machine-specific summary of the resolved toolchain. Stored on every BuildConfiguration so the fingerprint reflects “which compiler did this build use” without pinning the local absolute path.

Fields

tools: BTreeMap<String, String>

(kind -> "<spec>") , sorted alphabetically by tool key. Each entry records the user-visible spelling (clang++, /opt/llvm/bin/clang++, …); absolute resolved paths from PATH discovery are deliberately omitted.

sources: BTreeMap<String, String>

(kind -> source label) parallel to tools. Source labels are stable strings (cli, env, manifest, manifest-conditional, default).

compiler_wrapper: Option<CompilerWrapperSummary>

Optional compiler-cache wrapper (e.g. ccache, sccache) applied on top of the C++ compiler. None when no wrapper is selected; otherwise the kind/spec/source/version are folded into the configuration fingerprint so a build with a different wrapper choice reuses neither cache layer.

Implementations

impl ToolchainSummary

pub fn from_resolved(toolchain: &ResolvedToolchain) -> Self

Build a summary from a ResolvedToolchain. Storage is deterministic: tools iterate in sorted crate::ToolKind order via ResolvedToolchain::iter.

pub fn from_resolved_parts( toolchain: &ResolvedToolchain, wrapper: Option<&ResolvedCompilerWrapper>, ) -> Self

Build a summary from a ResolvedToolchain plus an optional compiler-cache wrapper. The wrapper is normalized into a CompilerWrapperSummary so the fingerprint captures the requested wrapper without leaking the local absolute path.

Trait Implementations

impl Clone for ToolchainSummary

fn clone(&self) -> ToolchainSummary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolchainSummary

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

Formats the value using the given formatter.

impl Default for ToolchainSummary

fn default() -> ToolchainSummary

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ToolchainSummary

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ToolchainSummary

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

impl Serialize for ToolchainSummary

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
