Struct llvm_mapper::map::MapCtx

#[non_exhaustive]
pub struct MapCtx { /* fields omitted */ }

A handle for various bits of state that are necessary for correct block and record mapping.

Internally, this is a mushy state object that may or may not contain sufficient information for parsing a particular block or record; hence the fallible access methods.

Block and record mapping operations are expected to update the supplied context, as appropriate.

Implementations

impl MapCtx

pub fn version(&self) -> Result<u64, MapCtxError>

Returns the version stored in this context, or an error if no version is available.

pub fn use_strtab(&self) -> Result<bool, MapCtxError>

A helper function for whether or not to use an associated string table for string lookups.

This corresponds to MODULE_CODE_VERSIONs of 2 and higher.

pub fn use_relative_ids(&self) -> Result<bool, MapCtxError>

A helper function for determining how operands are encoded.

This corresponds to MODULE_CODE_VERSIONs of 1 and higher.

pub fn strtab(&self) -> Result<&Strtab, MapCtxError>

Returns the string table stored in this context, or an error if no string table is available.

pub fn attribute_groups(&self) -> Result<&AttributeGroups, MapCtxError>

Returns the attribute groups stored in this context, or an error if not available.

Trait Implementations

impl Debug for MapCtx

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

Formats the value using the given formatter.

impl Default for MapCtx

fn default() -> MapCtx

Returns the “default value” for a type.
