)

pub fn log_invalidation(
    &mut self,
    tag: SbTag,
    range: AllocRange,
    current_span: &mut CurrentSpan<'_, '_, '_>
)

pub fn log_protector(
    &mut self,

    tag: SbTag,
    current_span: &mut CurrentSpan<'_, '_, '_>
)

pub fn get_logs_relevant_to(
    &self,
    tag: SbTag,
    protector_tag: Option<SbTag>
) -> Option<TagHistory>

pub fn grant_error<'tcx>(
    &self,
    derived_from: ProvenanceExtra,
    new: Item,
    alloc_id: AllocId,
    alloc_range: AllocRange,
    error_offset: Size,
    stack: &Stack
) -> InterpError<'tcx>

Report a descriptive error when new could not be granted from derived_from.

pub fn access_error<'tcx>(
    &self,
    access: AccessKind,
    tag: ProvenanceExtra,
    alloc_id: AllocId,
    alloc_range: AllocRange,
    error_offset: Size,
    stack: &Stack
) -> InterpError<'tcx>

Report a descriptive error when access is not permitted based on tag.

Trait Implementations

impl Clone for AllocHistory

fn clone(&self) -> AllocHistory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AllocHistory

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

Formats the value using the given formatter.

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.
