Variants

TooLarge

Fields

context: &'static str

nrows: usize

ncols: usize

bytes: usize

limit_bytes: usize

MissingRowChunk

Fields

RowMaterializationFailed

Fields

Reservation(MemoryReservationError)

The process-wide MemoryGovernor could not reserve the requested live footprint (or its checked byte size overflowed). Callers route to a chunked or matrix-free strategy.

Trait Implementations

impl Debug for MatrixMaterializationError

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

Formats the value using the given formatter.

impl Display for MatrixMaterializationError

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

Formats the value using the given formatter.

impl Error for MatrixMaterializationError

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<MemoryReservationError> for MatrixMaterializationError

fn from(source: MemoryReservationError) -> Self

Converts to this type from the input type.
