Struct InstructionAccount 

pub struct InstructionAccount {
    pub index_in_transaction: IndexOfAccount,
    pub index_in_caller: IndexOfAccount,
    pub index_in_callee: IndexOfAccount,
    pub is_signer: bool,
    pub is_writable: bool,
}

Contains account meta data which varies between instruction.

It also contains indices to other structures for faster lookup.

Fields

index_in_transaction: IndexOfAccount

Points to the account and its key in the TransactionContext

index_in_caller: IndexOfAccount

Points to the first occurrence in the parent InstructionContext

This excludes the program accounts.

index_in_callee: IndexOfAccount

Points to the first occurrence in the current InstructionContext

This excludes the program accounts.

is_signer: bool

Is this account supposed to sign

is_writable: bool

Is this account allowed to become writable

Trait Implementations

impl Clone for InstructionAccount

fn clone(&self) -> InstructionAccount

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InstructionAccount

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for InstructionAccount

fn eq(&self, other: &InstructionAccount) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
