func Ln ¶

func Ln(x any) (decimal.Decimal, error)

Ln returns the natural logarithm of x.

func Log ¶

func Log(x, y any) (decimal.Decimal, error)

Log returns the logarithms of y with base x. This is equivalent to log_x(y).

We use this formula:

             ln(y)
log_x(y)  =  ----
             ln(x)

func Max ¶

func Max(x ...any) (decimal.Decimal, error)

Max returns the maximum of x elements

func Min ¶

func Min(x ...any) (decimal.Decimal, error)

Min returns the minimum of x elements

func Mul ¶

func Mul(x, y any) (decimal.Decimal, error)

Mul returns the product of x and y

func NewEnv ¶

func NewEnv(observationTimestampNanoseconds uint64) environment

NewEnv returns a new environment with the default functions

func ParseDuration ¶

func ParseDuration(x string) (time.Duration, error)

ParseDuration parses a duration string into a time.ParseDuration

func Pow(x, y any) (decimal.Decimal, error)

Pow returns x, raised to the power of y

func ProcessCalculatedStreams ¶

func ProcessCalculatedStreams(lggr logger.Logger, channelDefinitions llotypes.ChannelDefinitions, streamAggregates protocol.StreamAggregates, observationTimestampNanoseconds uint64, optsCache *protocol.OptsCache)

ProcessCalculatedStreams evaluates expressions for each channel of the EVMABIEncodeUnpackedExpr format, appending the calculated streams to their channel definitions and writing the evaluated values into streamAggregates. It is version-agnostic: both the v30 and v31 plugins call it with their own outcome/precursor fields.

func ProcessCalculatedStreamsDryRun ¶

func ProcessCalculatedStreamsDryRun(expression string) error

ProcessCalculatedStreamsDryRun processes the calculated streams for the given expression against synthetic inputs and returns an error if it cannot be evaluated. Useful for validating expressions.
