Trait Implementations

impl ExplainExternal for SplTokenAccount

fn explain<S: ExternalExplainSink>( account: &AccountView<'_>, sink: &mut S, ) -> ProgramResult

Emit adapter-specific explain fields.

impl ExternalZeroCopy for SplTokenAccount

const OWNER: Option<Address>

Single expected owner program, when the adapter has one.

const MIN_LEN: usize = SPL_TOKEN_ACCOUNT_LEN

Minimum account data length accepted by this adapter.

type View<'a> = SplTokenAccountView<'a>

Guard-owned zero-copy view returned by this external adapter.

fn view<'a>(data: Ref<'a, [u8]>) -> Result<Self::View<'a>, ProgramError>

Build the adapter’s typed zero-copy view from an active account-data borrow. The borrow guard is consumed so the returned view can carry it.

const DISCRIMINATOR: Option<&'static [u8]> = None

Optional byte prefix/discriminator at offset 0.

fn validate(view: &AccountView<'_>) -> ProgramResult

Validate this external account. Override for multi-owner layouts, versioned dispatch, or custom invariants.
