Struct Layout Resolution

Source: src/compiler/layout.odin

Computes struct field offsets and AoS/SoA layouts.

Functions

init_layout_resolution {#init_layout_resolution}

Function: init_layout_resolution Initializes the global_structs map for struct layout resolution.

resolve_struct_layout {#resolve_struct_layout}

Function: resolve_struct_layout Resolves the byte layout of a struct declaration. For AoS layout, computes sequential field offsets with explicit padding enforcement. For SoA layout, computes cumulative per-element sizes for interleaved array storage. Registers the result in global_structs.

Types

Struct_Info {#struct_info}

Type: Struct_Info Stores resolved layout information for a struct declaration. Tracks name, byte size (AoS: with padding, SoA: per-element), alignment, layout kind, field metadata, and SoA block size.

Struct_Field_Info {#struct_field_info}

Type: Struct_Field_Info Stores resolved layout information for a single struct field. Tracks the field name, its Width type, and byte offset (AoS) or cumulative size index (SoA).

Constants

width_to_size {#width_to_size}

Constant: width_to_size Maps Width enum values to their byte sizes for use during struct layout resolution and field offset computation.

Variables

global_structs {#global_structs}

Variable: global_structs Global registry mapping struct names to their resolved Struct_Info. Populated by resolve_struct_layout and queried during constant evaluation.
