Enum LoaderKind 

pub enum LoaderKind {
    BpfLoader2,
    Upgradeable,
    LoaderV4,
    Unknown,
}

Which loader manages a given program account. The classifier matches against the base58-encoded owner pubkey as it comes out of the Solana JSON-RPC response; callers don’t need to decode to raw bytes first.

Variants

BpfLoader2

BPFLoader2111… — account data is the ELF directly.

Upgradeable

BPFLoaderUpgradeab1e… — Program + ProgramData split.

LoaderV4

LoaderV411… — 48-byte header then ELF.

Unknown

Owner doesn’t match any known loader. Caller should surface the actual owner string to the user.

Trait Implementations

impl Clone for LoaderKind

fn clone(&self) -> LoaderKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoaderKind

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

Formats the value using the given formatter.

impl PartialEq for LoaderKind

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