Struct RustcInvocation 

pub struct RustcInvocation { /* private fields */ }

Implementations

impl RustcInvocation

pub fn dep_info_command( &self, output: &Path, ) -> Result<DepInfoCommand, BypassReason>

Replace the original output flags with a single explicit dep-info file.

pub fn discover_inputs( &self, dep_info: &RustcDepInfo, working_dir: &Path, ) -> Result<DiscoveredInputs, BypassReason>

Hash dep-info sources plus every direct compiler input already modeled by the invocation (--extern artifacts and custom target specs).

impl RustcInvocation

pub fn parse(arguments: &[OsString]) -> Result<Self, BypassReason>

Parse rustc’s arguments, excluding the compiler executable supplied as the first argument to RUSTC_WRAPPER.

Any flag whose cache semantics are not modeled returns a bypass reason instead of guessing. A successful parse only admits the initial rlib/rmeta cacheability tier.

pub fn source(&self) -> &Path

Return the source input passed to rustc.

pub fn outputs(&self, working_dir: &Path) -> Result<RustcOutputs, BypassReason>

Resolve the rlib/rmeta files produced by this invocation.

The initial cache tier requires one output directory so its artifact can be represented by one protocol directory and restored atomically later.

pub fn action( &self, context: ActionContext, ) -> Result<RustcAction, BypassReason>

Build canonical action bytes after precise input discovery has run.

context.inputs must contain the source, every explicit extern, and every additional source or environment-generated input discovered from dep-info.

pub fn invocation_digest( &self, context: &ActionContext, ) -> Result<CacheDigest, BypassReason>

Fingerprint the modeled invocation before dependency contents are known.

pub fn prediction( &self, context: &ActionContext, discovered: &DiscoveredInputs, ) -> Result<RustcInputPrediction, BypassReason>

Capture normalized dependency paths for a future invocation that has no dep-info file yet.
