Struct rustc_mir_transform::check_unsafety::UnsafetyChecker

pub struct UnsafetyChecker<'a, 'tcx> {
    body: &'a Body<'tcx>,
    body_did: LocalDefId,
    violations: Vec<UnsafetyViolation>,
    source_info: SourceInfo,

Fields

body: &'a Body<'tcx>

body_did: LocalDefId

violations: Vec<UnsafetyViolation>

source_info: SourceInfo

tcx: TyCtxt<'tcx>

param_env: ParamEnv<'tcx>

used_unsafe: FxHashSet<HirId>

Mark an unsafe block as used, so we don’t lint it.

inherited_blocks: Vec<(HirId, bool)>

Implementations

impl<'a, 'tcx> UnsafetyChecker<'a, 'tcx>

fn new(
    body: &'a Body<'tcx>,
    body_did: LocalDefId,
    tcx: TyCtxt<'tcx>,
    param_env: ParamEnv<'tcx>
) -> Self

impl<'a, 'tcx> UnsafetyChecker<'a, 'tcx>

fn require_unsafe(
    &mut self,
    kind: UnsafetyViolationKind,
    details: UnsafetyViolationDetails
)

fn register_violations(
    &mut self,
    violations: &[UnsafetyViolation],
    unsafe_blocks: &[(HirId, bool)]
)

fn check_mut_borrowing_layout_constrained_field(
    &mut self,
    place: Place<'tcx>,
    is_mut_use: bool
)

fn check_target_features(&mut self, func_did: DefId)

Checks whether calling func_did needs an unsafe context or not, i.e. whether the called function has target features the calling function hasn’t.

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.
