Enum Error 

#[non_exhaustive]
pub enum Error {
    PoolExhausted,

}

Main error type for Parallax operations.

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.

PoolExhausted

Memory pool is exhausted (no slots available).

BufferPool(String)

Buffer pool error (no pool configured or pool unavailable).

AllocationFailed(String)

Memory allocation failed.

InvalidSegment(String)

Invalid memory segment operation.

ValidationFailed(String)

Buffer validation failed (rkyv).

InvalidCaps(String)

Invalid caps / type mismatch.

Config(String)

Configuration error.

Pipeline(String)

Pipeline error.

Element(String)

Element error.

Io(Error)

I/O error.

System(Errno)

System call error (via rustix).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Errno> for Error

fn from(source: Errno) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<UnsupportedPixelFormat> for Error

fn from(e: UnsupportedPixelFormat) -> Self

Converts to this type from the input type.
