Required Associated Types

type Value

Value Type.

Provided Methods

fn visit_account( self, account: impl AccountAccess, ) -> Result<Self::Value, DecodeError>

Visit an account.

fn visit_anchor_cpi_events<'a>( self, events: impl AnchorCPIEventsAccess<'a>, ) -> Result<Self::Value, DecodeError>

Visit Anchor CPI events.

fn visit_owned_data( self, program_id: &Pubkey, data: &[u8], ) -> Result<Self::Value, DecodeError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
