A stable recoverable error emitted by checked numeric, byte, and tensor operations.
Signature
enum DataError { ... }Each case name and description comes from the Rust SDK data-error registry.
Cases
TypeMismatch- An operation requires operands with the same declared element type.
InvalidLiteral- Text is not a valid literal of the requested type.
InvalidUtf8- Bytes are not valid UTF-8 where a text value is required.
Overflow- A value or checked integer operation exceeds the destination range.
NonFinite- Infinity and NaN cannot enter a portable data value.
InexactConversion- A conversion would round, truncate, or discard a signed zero.
DivisionByZero- Division or remainder has a zero divisor.
InvalidShape- Shape, rank, or buffer length is not a valid tensor layout.
ShapeMismatch- Shapes cannot participate in the requested operation.
Bounds- An index is outside the requested value.
InvalidSlice- Slice selectors are malformed, including a zero step.
InvalidMetadata- Decoded media metadata disagrees with its payload.
AllocationLimit- A checked allocation exceeds the portable data limit.
Examples
Handle invalid UTF-8
Decoding reports InvalidUtf8 instead of replacing malformed bytes.
