Network.Solana.Core.Instruction

A single program invocation: which program to call, the accounts it may read or write, and the input bytes to pass it.

Build an Instruction from a program id, account metas, and Binary-encodable instruction data.

Address of the program that executes this instruction.

List of metadata describing accounts that should be passed to the program.

Bytes selecting which instruction of the program to invoke, plus any arguments it needs.

Each account required by an instruction must be provided as an AccountMeta that contains:

Raw instruction input bytes. Show renders them in Base64.

Replace each pubkey referenced by an instruction with its index into the given account-key table. Left when a key is not present in the table, or sits at position 256 or beyond -- a compiled index is a single byte, so such a key is rejected rather than silently wrapped into the wrong index (mirroring the Rust SDK's CompileError::AccountIndexOverflow).

The structure of a compiled instruction.

Compilation failure, carrying a message: an instruction references an account key that is missing from the message's account table, an account or lookup-table index does not fit in a byte, or a signing key does not match the message's required signers.
