Struct ValidatedFrame 

pub struct ValidatedFrame<'a, T> { /* private fields */ }

A frame whose accounts have been validated.

Implementations

impl<'a, T> ValidatedFrame<'a, T>

pub fn execute_with_args<A, R, F>( self, args: &A, f: F, ) -> Result<R, ProgramError>

where F: FnOnce(&mut ExecutionContext<'a, '_, T>, &A) -> Result<R, ProgramError>,

Execute with access to typed instruction args.

This is the arg-aware counterpart of execute().

impl<'a, T> ValidatedFrame<'a, T>

pub fn program_id(&self) -> &Address

Program ID.

pub fn ix_data(&self) -> &[u8]

Instruction data.

pub fn accounts(&self) -> &T

Access the resolved and validated accounts.

pub fn execute<R, F>(self, f: F) -> Result<R, ProgramError>

where F: FnOnce(&mut ExecutionContext<'a, '_, T>) -> Result<R, ProgramError>,

Execute the instruction logic.

The closure receives an ExecutionContext with mutable access to the validated accounts and mutable borrow tracking.

validated.execute(|ctx| {
    let vault_data = ctx.borrow_mut(1)?;
    // ... mutate state ...
    Ok(())
})?;
