Enum ProgramCacheEntryType

pub enum ProgramCacheEntryType {
    FailedVerification(ProgramRuntimeEnvironment),
    Closed,
    DelayVisibility,
    Unloaded(ProgramRuntimeEnvironment),
    Loaded(Executable<InvokeContext<'static>>),
    Builtin(BuiltinProgram<InvokeContext<'static>>),
}

Actual payload of ProgramCacheEntry.

Variants

FailedVerification(ProgramRuntimeEnvironment)

Tombstone for programs which currently do not pass the verifier but could if the feature set changed.

Closed

Tombstone for programs that were either explicitly closed or never deployed.

It’s also used for accounts belonging to program loaders, that don’t actually contain program code (e.g. buffer accounts for LoaderV3 programs).

DelayVisibility

Tombstone for programs which have recently been modified but the new version is not visible yet.

Unloaded(ProgramRuntimeEnvironment)

Successfully verified but not currently compiled.

It continues to track usage statistics even when the compiled executable of the program is evicted from memory.

Loaded(Executable<InvokeContext<'static>>)

Verified and compiled program

Builtin(BuiltinProgram<InvokeContext<'static>>)

A built-in program which is not stored on-chain but backed into and distributed with the validator
