Struct PassCtx 

pub(crate) struct PassCtx<'sess> {
    session: &'sess Session,
    body_mir_opt_level: usize,
}

Fields

session: &'sess Session

Prefer Self::mir_opt_level to Session::mir_opt_level to account for overrides.

body_mir_opt_level: usize

The MIR optimization level for this body; may be overridden by #[optimize].

Implementations

impl<'sess> PassCtx<'sess>

pub(crate) fn mir_opt_level(&self) -> usize

feature must be a language feature.

pub fn record_trimmed_def_paths(&self)

Record the fact that we called trimmed_def_paths, and do some checking about whether its cost was justified.

pub fn enable_internal_lints(&self) -> bool

Returns true if internal lints should be added to the lint store - i.e. if -Zunstable-options is provided and this isn’t rustdoc (internal lints can trigger errors to be emitted under rustdoc).

pub fn instrument_coverage(&self) -> bool

pub fn instrument_coverage_branch(&self) -> bool

pub fn instrument_coverage_condition(&self) -> bool

pub fn coverage_options(&self) -> &CoverageOptions

Provides direct access to the CoverageOptions struct, so that individual flags for debugging/testing coverage instrumetation don’t need separate accessors.

pub fn is_sanitizer_cfi_enabled(&self) -> bool

pub fn is_sanitizer_cfi_canonical_jump_tables_disabled(&self) -> bool

pub fn is_sanitizer_cfi_canonical_jump_tables_enabled(&self) -> bool

pub fn is_sanitizer_cfi_generalize_pointers_enabled(&self) -> bool

Check whether this compile session and crate type use static crt.

pub fn target_can_use_split_dwarf(&self) -> bool

Returns true if the target can use the current split debuginfo configuration.

pub fn target_filesearch(&self) -> &FileSearch

pub fn host_filesearch(&self) -> &FileSearch

pub fn wasm_proc_macro_filesearch(&self) -> &FileSearch

pub fn get_tools_search_paths(&self, self_contained: bool) -> Vec<PathBuf>

Returns a list of directories where target-specific tool binaries are located. Some fallback directories are also returned, for example if --sysroot is used but tools are missing (#125246): we also add the bin directories to the sysroot where rustc is located.

pub fn is_rust_2015(&self) -> bool

Is this edition 2015?

pub fn at_least_rust_2018(&self) -> bool

Are we allowed to use features from the Rust 2018 edition?

pub fn at_least_rust_2021(&self) -> bool

Are we allowed to use features from the Rust 2021 edition?

pub fn at_least_rust_2024(&self) -> bool

Are we allowed to use features from the Rust 2024 edition?

pub fn needs_plt(&self) -> bool

Returns true if we should use the PLT for shared library calls.

pub fn emit_lifetime_markers(&self) -> bool

Checks if LLVM lifetime markers should be emitted.

pub fn diagnostic_width(&self) -> usize

pub fn default_visibility(&self) -> SymbolVisibility

Returns the default symbol visibility.

pub fn resolve_path( &self, path: impl Into<PathBuf>, span: Span, ) -> Result<PathBuf, Diag<'_>>

Resolves a path mentioned inside Rust code, returning an absolute path.

This unifies the logic used for resolving include_*! and debugger visualizers.

pub fn verbose_internals(&self) -> bool

pub fn print_llvm_stats_json(&self) -> Option<&String>

pub fn verify_llvm_ir(&self) -> bool

pub fn binary_dep_depinfo(&self) -> bool

pub fn mir_opt_level(&self) -> usize

pub fn lto(&self) -> Lto

Calculates the flavor of LTO to use for this compilation.

pub fn panic_strategy(&self) -> PanicStrategy

Returns the panic strategy for this compile session. If the user explicitly selected one using ‘-C panic’, use that, otherwise use the panic strategy defined by the target.

pub fn fewer_names(&self) -> bool

pub fn unstable_options(&self) -> bool

pub fn is_nightly_build(&self) -> bool

pub fn overflow_checks(&self) -> bool

pub fn ub_checks(&self) -> bool

pub fn contract_checks(&self) -> bool

Returns the DWARF version passed on the CLI or the default for the target.

pub fn stack_protector(&self) -> StackProtector

pub fn branch_protection(&self) -> Option<BranchProtection>

Returns the -Zbranch-protection info. Note that it is adjusted to the current target, e.g. some targets only support certain Pointer Authentication Code keys.

Accessing the session’s unstable branch_protection option fields directly is linted against.

pub fn must_emit_unwind_tables(&self) -> bool

pub fn codegen_units(&self) -> CodegenUnits

Returns the number of codegen units that should be used for this compilation

pub fn teach(&self, code: ErrCode) -> bool

pub fn edition(&self) -> Edition

pub fn link_dead_code(&self) -> bool

pub fn apple_deployment_target(&self) -> OSVersion

Get the deployment target on Apple platforms based on the standard environment variables, or fall back to the minimum version supported by rustc.

This should be guarded behind if sess.target.is_like_darwin.

pub fn sanitizers(&self) -> SanitizerSet

pub fn pointer_authentication(&self) -> bool

pub fn pointer_authentication_functions(&self) -> Option<&PointerAuthSchema>

pub fn pointer_authentication_init_fini(&self) -> Option<&PointerAuthSchema>

Trait Implementations

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
