Types ¶
type BoundedType ¶
type BoundedType interface {
Type
MinVal() *big.Rat // MinVal returns the smallest value of this type.
MaxVal() *big.Rat // MaxVal returns the largest value of this type.
}
BoundedType represents a numeric type with boundaries on its value.
type CodeInstruction ¶
type CodeInstruction func(*Thread)
type DivByZeroError ¶
type DivByZeroError struct{}
DivByZeroError is used to abort a thread when a division by zero occurs.
func (DivByZeroError) Error ¶
func (DivByZeroError) Error() string
type Frame ¶
type IndexError ¶
type IndexError struct {
Idx, Len int64
}
IndexError is used to abort a thread when an indexed expression is out of bounds.
func (IndexError) Error ¶
func (e IndexError) Error() string
type KeyError ¶
type KeyError struct {
Key interface{}
}
KeyError is used to abort a thread when invalid key indices are used in a map expression.
type NegativeCapacityError ¶
type NegativeCapacityError struct {
Len int64
}
NegativeCapacityError is used to abort a thread when a negative capacity is used when creating a Slice.
func (NegativeCapacityError) Error ¶
func (e NegativeCapacityError) Error() string
type NegativeLengthError ¶
type NegativeLengthError struct {
Len int64
}
NegativeLengthError is used to abort a thread when a negative length is used when creating a Slice.
func (NegativeLengthError) Error ¶
func (e NegativeLengthError) Error() string
type NilPointerError ¶
type NilPointerError struct{}
NilPointerError is used to abort a thread when a nil pointer is dereferenced.
func (NilPointerError) Error ¶
func (NilPointerError) Error() string
type SliceError ¶
type SliceError struct {
Lo, Hi, Cap int64
}
SliceError is used to abort a thread when invalid indices are used for a slice manipulation of a Slice, Array or String.
func (SliceError) Error ¶
func (e SliceError) Error() string
type Thread ¶
type Thread struct {
PC uint // Program Counter
Frame *Frame // The execution frame of this function. This remains the same throughout a function invocation.
// contains filtered or unexported fields
}
type Type ¶
type Type interface {
// Compat returns whether this type is compatible with another type.
// If conv is false, this is normal compatibility, where two named types are compatible only if they are the same named type.
// If conv if true, this is conversion compatibility, where two named types are conversion compatible if their definitions are conversion compatible.
Compat(t Type, conv bool) bool // TODO: Deal with recursive types
// Lit returns this type's literal.
// If this is a named type, this is the unnamed underlying type.
// Otherwise, this is an identity operation.
Lit() Type
// IsBoolean returns true if this is a boolean type.
IsBoolean() bool
// IsInteger returns true if this is an integer type.
IsInteger() bool
// IsFloat returns true if this is a floating type.
IsFloat() bool
// IsIdeal returns true if this represents an ideal value.
IsIdeal() bool
// Zero returns a new zero value of this type.
Zero() Value
// String returns the string representation of this type.
String() string
}
Type is the common interface for all supported types
type Value ¶
type Value interface {
// String returns the string representation of this value.
String() string
// Assign copies another value into this one.
// It should assume that the other value satisfies the same specific value interface (BoolValue, etc.),
// but must not assume anything about its specific type.
Assign(t *Thread, v Value)
}
