Enum PpuSnapshotError 

#[non_exhaustive]
pub enum PpuSnapshotError {
    Truncated(usize),
    UnsupportedVersion(u8),
    InvalidRegion(u8),
    InvalidPresence(u8),
}

Errors returned by Ppu::restore.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Truncated(usize)

Blob is too short for the version-1 schema.

UnsupportedVersion(u8)

The blob’s version byte is not understood by this build.

InvalidRegion(u8)

Region tag was not one of 0 (NTSC), 1 (PAL), 2 (Dendy).

InvalidPresence(u8)

Optional struct presence byte was something other than 0 or 1.

Trait Implementations

impl Debug for PpuSnapshotError

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

Formats the value using the given formatter.

impl Display for PpuSnapshotError

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

impl Error for PpuSnapshotError

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.
