Struct TypeSpec 

pub struct TypeSpec {
    pub rid: u32,
    pub token: Token,
    pub offset: usize,
    pub signature: SignatureTypeSpec,
}

Represents an owned TypeSpec table entry with resolved references and parsed signatures.

The TypeSpec table defines type specifications through signatures, providing the foundation for complex type definitions including generic types, arrays, pointers, and type modifiers. This struct contains fully resolved and owned data from the raw table entries.

Fields Overview

• rid: The 1-based row identifier within the TypeSpec table
• token: The metadata token for this TypeSpec entry
• offset: Byte offset of the signature within the blob heap
• signature: Fully parsed type specification signature

Type Specifications

TypeSpec entries define types through their signatures and are used for:

• Generic type instantiations (e.g., List<T>)
• Array types with specific dimensions
• Pointer and reference types
• Modified types (e.g., const, volatile)

Usage in Metadata

TypeSpec entries are referenced by:

• crate::metadata::tables::MethodDefRaw - Method signatures
• crate::metadata::tables::Field - Field type specifications
• crate::metadata::tables::MemberRef - Member references
• Other tables requiring complex type definitions

Fields

rid: u32

The 1-based row identifier within the TypeSpec table.

This identifier uniquely identifies the TypeSpec entry within the table and is used for cross-references from other metadata tables.

token: Token

The metadata token for this TypeSpec entry.

Tokens provide a consistent way to reference metadata entries across different contexts and are used in IL instructions and other metadata.

offset: usize

Byte offset of the type signature within the blob heap.

This offset points to the location in the blob heap where the type specification signature is stored in its binary encoded form.

signature: SignatureTypeSpec

The fully parsed type specification signature.

Contains the complete type definition including generic parameters, array dimensions, pointer levels, and type modifiers. This signature defines the exact type being specified.
