Enum ProgramError 

pub enum ProgramError {
    Json(String),
    TooNew {
        found: u32,
        supported: u32,
    },
    HashMismatch {
        stored: u64,
        computed: u64,
    },
}

Why a serialized Program failed to load.

Variants

Json(String)

The JSON didn’t parse or didn’t match the bundle shape.

TooNew

The bundle’s program_version is newer than this binary supports.

Fields

found: u32

The bundle’s revision.

supported: u32

This binary’s PROGRAM_VERSION.

HashMismatch

The stored hash doesn’t match the recomputed one — the bundle was hand-edited or corrupted (T3002).

Fields

stored: u64

The hash stored in the bundle.

computed: u64

The hash recomputed from the versioned bundle content.

Trait Implementations

impl Clone for ProgramError

fn clone(&self) -> ProgramError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProgramError

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

Formats the value using the given formatter.

impl Display for ProgramError

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

Formats the value using the given formatter.

impl Eq for ProgramError

impl Error for ProgramError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ProgramError

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

Equality operator ==.

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

Inequality operator !=.
