Context wrapper classification for an instruction function.

Validates that an account's address matches the expected [`Id::ID`].

Protocol-owned account behavior attached via `#[account(my_behavior(...))]`. # Writing a behavior module A behavior group `#[account(foo(a = x, b =

8-byte-aligned buffer for constructing RuntimeAccount + data. Uses `Vec<u64>` to guarantee alignment >= 8, which satisfies RuntimeAccount's alignment

Declares the number of accounts consumed by a struct during parsing. Implemented by: `#[derive(Accounts)]` macro. Used by: `dispatch!` macro to size

Bounds-checked data writes for unchecked account slots. This keeps the common "write these bytes at this offset" path safe without exposing a long-li

Internal account descriptor for client macro generation.

Fragment submitted by `#[account]`; uses a fn pointer to avoid static alloc.

Initialization behavior for account types. Implemented on the behavior target (Token, Mint, `#[account]` types), not on wrapper types (`Account<T>`,

Layout descriptor for zero-copy account wrappers. Maps a wrapper type to its schema (for validation) and target (for Deref). `DATA_OFFSET` is 0 for e

Unified validation, construction, and header flag consts for account wrapper types. All implementors must be `#[repr(transparent)]` over `AccountView

Fixed-size repeated account group. `AccountsArray<T, N>` always consumes exactly `N * T::COUNT` accounts, where `T` is another `#[derive(Accounts)]`

Fragment submitted by `#[derive(Accounts)]`; carries account metadata for IDL.

Instruction-wide execution plan.

Unified address verification trait. Both exact address matches (`Address`) and PDA seed specs (`SeedSet` types) implement this trait, letting the der

Per-arg classification: fixed-size or dynamic (compact) decode.

Convert a typed account wrapper to its underlying [`AccountView`]. All account types (`Account<T>`, `Signer`, `UncheckedAccount`, etc.) implement thi

Trait for types that can execute ATA program CPI calls. Implemented by `Program<AssociatedTokenProgram>`. Import this trait to call `.create()` and `
