Represents the kind of an Error.

This also stores the unique information tied to the error report.

Variants

InvalidRadix(u8)

Returned on trying to create a Radix from an invalid u8 representation.

InvalidStringRepr

Returned whenever trying to parse an invalid string representation for an ApInt.

Fields of InvalidStringRepr

input: String	The string storing the invalid representation of the int for the given radix.
radix: Radix	The radix that was used.
pos_char: Option<(usize, char)>	An optional index and character when encountering an invalid character.

InvalidBitAccess

Returned on trying to access an invalid bit position.

Fields of InvalidBitAccess

pos: BitPos	The invalid bit position that was tried to access.
width: BitWidth	The upper bound for valid bit positions in this context.

InvalidShiftAmount

Returned on trying to shift with an invalid shift amount.

Fields of InvalidShiftAmount

shift_amount: ShiftAmount	The invalid shift amount.
width: BitWidth	The bit width for which this shift amount of invalid.

ValueUnrepresentable

Returns on trying to cast an ApInt to a primitive type that can not represent the value represented by the ApInt.

Fields of ValueUnrepresentable

value: ApInt	The ApInt that the user wanted to represent as the given PrimitiveTy.
destination_ty: PrimitiveTy	The PrimitiveTy that the user wanted for representing the given ApInt.

UnmatchingBitwidth(BitWidth, BitWidth)

Returned on violation of matching bitwidth constraints of operations.

InvalidBitWidth(usize)

Returned on trying to create a BitWidth from an invalid usize representation.

TruncationBitWidthTooLarge

Returned on truncating an ApInt with a bitwidth greater than the current one.

Fields of TruncationBitWidthTooLarge

target: BitWidth	The target bit width.
current: BitWidth	The current actual bit width.

ExtensionBitWidthTooSmall

Returned on extending an ApInt with a bitwidth less than the current one.

Fields of ExtensionBitWidthTooSmall

target: BitWidth	The target bit width.
current: BitWidth	The current actual bit width.

ExpectedNonEmptyDigits

Returned on constructing an ApInt from an empty iterator of Digits.
