Constants 2

const DefaultMaxCharacterLength 

1const DefaultMaxCharacterLength = 64
source

DefaultMaxCharacterLength defines the default maximum character length used in validation of identifiers including the client, connection, port and channel identifiers.

NOTE: this restriction is specific to this golang implementation of IBC. If your use case demands a higher limit, please open an issue and we will consider adjusting this restriction.

Variables 2

var DefaultMaxPortCharacterLength 

1var DefaultMaxPortCharacterLength = 128
source

DefaultMaxPortCharacterLength defines the default maximum character length used in validation of port identifiers.

var IsValidID 

1var IsValidID = regexp.MustCompile(`^[a-zA-Z0-9\.\_\+\-\#\[\]\<\>]+$`).MatchString
source

IsValidID defines regular expression to check if the string consist of characters in one of the following categories only: - Alphanumeric - `.`, `_`, `+`, `-`, `#` - `[`, `]`, `<`, `>`

Functions 8

func ClientIdentifierValidator 

1func ClientIdentifierValidator(id string) error
source

ClientIdentifierValidator is the default validator function for Client identifiers. A valid Identifier must be between 4-64 characters and only contain alphanumeric and some allowed special characters (see IsValidID).

func PacketAcknowledgementKey 

1func PacketAcknowledgementKey(clientID string, sequence uint64) []byte
source

PacketAcknowledgementKey returns the store key of under which a packet acknowledgement is stored. clientID must be a generated identifier, not provided externally so key collisions are not possible.

func PacketAcknowledgementPrefixKey 

1func PacketAcknowledgementPrefixKey(clientID string) []byte
source

PacketAcknowledgementPrefixKey returns the store key prefix under which packet acknowledgements for a particular channel are stored. clientID must be a generated identifier, not provided externally so key collisions are not possible.

func PacketCommitmentKey 

1func PacketCommitmentKey(clientID string, sequence uint64) []byte
source

PacketCommitmentKey returns the store key of under which a packet commitment is stored. clientID must be a generated identifier, not provided externally so key collisions are not possible.

func PacketCommitmentPrefixKey 

1func PacketCommitmentPrefixKey(clientID string) []byte
source

PacketCommitmentPrefixKey returns the store key prefix under which packet commitments for a particular client are stored. clientID must be a generated identifier, not provided externally so key collisions are not possible.

func PacketReceiptKey 

1func PacketReceiptKey(clientID string, sequence uint64) []byte
source

PacketReceiptKey returns the store key of under which a packet receipt is stored. clientID must be a generated identifier, not provided externally so key collisions are not possible.

func PacketReceiptPrefixKey 

1func PacketReceiptPrefixKey(clientID string) []byte
source

PacketReceiptPrefixKey returns the store key prefix under which packet receipts for a particular channel are stored. clientID must be a generated identifier, not provided externally so key collisions are not possible.

func PortIdentifierValidator 

1func PortIdentifierValidator(id string) error
source

PortIdentifierValidator is the default validator function for Port identifiers. A valid Identifier must be between 2-64 characters and only contain alphanumeric and some allowed special characters (see IsValidID).
