Functions

func FullCapabilities 

func FullCapabilities() map[Capability]bool

FullCapabilities returns a mapping of all known relayer features to true, indicating that all features are supported. FullCapabilities returns a new map every time it is called, so callers are free to set one value to false if they support everything but one or two features.

Types

type Capability 

type Capability int

Capability indicates a relayer's support of a given feature. 

const (
	TimestampTimeout Capability = iota
	HeightTimeout

	// Whether the relayer supports a one-off flush packets or flush acknowledgements command.
	FlushPackets
	FlushAcknowledgements
)

The list of relayer capabilities that ibctest understands.
