Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.
Think of it as a tool or abstraction that removes friction from shipping on Solana.
Place the term inside its Solana layer so the definition is easier to reason about.
Anchor, local validators, explorers, SDKs, and testing workflows.
Turn the term from vocabulary into something operational for product and engineering work.
This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

IDL Generation (idl-generation) Category: Developer Tools Definition: Process of producing an Interface Definition Language file from a Solana program's source code. Anchor auto-generates IDLs from Rust program definitions. Shank and Codama provide IDL generation for non-Anchor programs. IDLs enable automatic TypeScript/Python client generation and human-readable instruction decoding. Related: IDL (Interface Definition Language), Anchor Framework, Codama, Shank
Use glossary context, relationships, mental models, and builder paths to get structured answers instead of generic chat output.
Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.
The Copilot will answer using the current term, related concepts, mental models, and the surrounding glossary graph.
These branches show which concepts this term touches directly and what sits one layer beyond them.
Interface Definition Language—a JSON specification that describes a program's instructions, accounts, types, and error codes. Anchor auto-generates the IDL from the program source code. Client libraries (TypeScript, Python) use the IDL to serialize/deserialize instruction data and accounts, enabling type-safe interaction without manual encoding.
The most popular framework for building Solana programs in Rust. Anchor provides macros (#[program], #[account], #[derive(Accounts)]) that auto-generate boilerplate for account validation, serialization, discriminators, and error handling. It includes a CLI (anchor init/build/test/deploy), IDL generation, and TypeScript client generation. Reduces program code by ~80% compared to native development.
A code generation toolchain that takes a Solana program's IDL and generates fully-typed client SDKs in multiple languages. Codama processes IDLs produced by Shank or Anchor and emits TypeScript clients. It is the successor of the Kinobi project and is commonly used in the Pinocchio + Shank + Codama workflow for native Solana program development.
A Rust macro-based tool for generating IDL files from native Solana programs that do not use Anchor. Shank provides attribute macros like #[derive(ShankAccount)] and #[derive(ShankInstruction)] that annotate program code to produce IDL output compatible with Codama/Kinobi for client generation. A key component of the Pinocchio + Shank + Codama workflow.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.

The Anchor macro applied to structs to define on-chain account data layouts. `#[account]` auto-derives Borsh serialization, adds an 8-byte discriminator prefix (SHA-256 of 'account:<Name>'), and implements space calculation. Optional attributes: `#[account(zero_copy)]` for zero-copy deserialization of large accounts.
The Anchor macro that defines the accounts struct for an instruction. Each field specifies an account with validation constraints. Account types include: `Account<'info, T>` (deserialized), `Signer<'info>` (must sign), `Program<'info, T>` (program reference), `SystemAccount<'info>`, and `UncheckedAccount<'info>` (no validation, use carefully).
Declarative validation rules on Anchor account fields. Key constraints: `#[account(mut)]` (writable), `#[account(init, payer=x, space=n)]` (create), `#[account(seeds=[...], bump)]` (PDA validation), `#[account(has_one=field)]` (field equality), `#[account(constraint = expr)]` (custom boolean), `#[account(close=target)]` (close and reclaim rent).
