Struct MapCtx 

#[non_exhaustive]
pub struct MapCtx<'ctx> {
    pub version: u64,
    pub datalayout: &'ctx DataLayout,
    pub section_table: &'ctx [String],
    pub gc_table: &'ctx [String],
    pub strtab: &'ctx Strtab,
    pub attribute_groups: &'ctx AttributeGroups,
    pub attributes: &'ctx Attributes,
    pub type_table: &'ctx TypeTable,
    pub comdats: &'ctx [Comdat],
}

A handle for various bits of state that are necessary for correct block and record mapping in the context of a particular IR module.

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

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

version: u64

The MODULE_CODE_VERSION for the IR module being mapped.

datalayout: &'ctx DataLayout

The datalayout specification.

section_table: &'ctx [String]

The section table.

gc_table: &'ctx [String]

The GC table.

strtab: &'ctx Strtab

The string table.

attribute_groups: &'ctx AttributeGroups

Any attribute groups.

attributes: &'ctx Attributes

Any raw attributes.

type_table: &'ctx TypeTable

The type table.

comdats: &'ctx [Comdat]

The COMDAT list.

Implementations

impl MapCtx<'_>

pub fn use_strtab(&self) -> bool

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) -> bool

A helper function for determining how operands are encoded.

This corresponds to MODULE_CODE_VERSIONs of 1 and higher.

Trait Implementations

impl<'ctx> Debug for MapCtx<'ctx>

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

Formats the value using the given formatter.
