Struct InstrContext

pub struct InstrContext {
    pub program_id: Vec<u8>,
    pub accounts: Vec<AcctState>,
    pub instr_accounts: Vec<InstrAcct>,
    pub data: Vec<u8>,
    pub cu_avail: u64,
    pub txn_context: Option<TxnContext>,
    pub slot_context: Option<SlotContext>,
    pub epoch_context: Option<EpochContext>,
}

The execution context of a program invocation (aka instruction). Contains all required information to independently replay an instruction. Also includes partial transaction context.

Fields

program_id: Vec<u8>

The address of the program invoked. (32 bytes)

accounts: Vec<AcctState>

Account state accessed by the instruction. This may include indirect accesses like sysvars.

instr_accounts: Vec<InstrAcct>

Account access list for this instruction (refers to above accounts list)

data: Vec<u8>

The input data passed to program execution.

cu_avail: u64

txn_context: Option<TxnContext>

slot_context: Option<SlotContext>

epoch_context: Option<EpochContext>

Trait Implementations

impl Clone for InstrContext

fn clone(&self) -> InstrContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstrContext

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

Formats the value using the given formatter.

impl Default for InstrContext

fn default() -> Self

Returns the “default value” for a type.

impl Message for InstrContext

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for InstrContext

fn eq(&self, other: &InstrContext) -> 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.
