Functions ¶
func Lib ¶
Lib returns a cel.EnvOption to configure extended functions to ease use of maps and timestamps.
As (Macro)
The as macro is syntactic sugar for [val].map(var, function)[0].
Examples:
{"a":1, "b":2}.as(v, v.a == 1) // return true
{"a":1, "b":2}.as(v, v) // return {"a":1, "b":2}
{"a":1, "b":2}.as(v, v.with({"c":3})) // return {"a":1, "b":2, "c":3}
{"a":1, "b":2}.as(v, [v, v]) // return [{"a":1, "b":2}, {"a":1, "b":2}]
With ¶
Returns the receiver's value with the value of the parameter updating or adding fields:
<map<K,V>>.with(<map<K,V>>) -> <map<K,V>>
Examples:
{"a":1, "b":2}.with({"a":10, "c":3}) // return {"a":10, "b":2, "c":3}
With Replace ¶
Returns the receiver's value with the value of the parameter replacing existing fields:
<map<K,V>>.with_replace(<map<K,V>>) -> <map<K,V>>
Examples:
{"a":1, "b":2}.with_replace({"a":10, "c":3}) // return {"a":10, "b":2}
With Update ¶
Returns the receiver's value with the value of the parameter updating the map without replacing any existing fields:
<map<K,V>>.with_update(<map<K,V>>) -> <map<K,V>>
Examples:
{"a":1, "b":2}.with_update({"a":10, "c":3}) // return {"a":1, "b":2, "c":3}
Is Zero ¶
Returns whether the receiver is the zero time:
<timestamp>.is_zero() -> <bool>
Examples:
timestamp("0001-01-01T00:00:00Z").is_zero() // return true
timestamp("0001-01-01T00:00:01Z").is_zero() // return false
Debug ¶
The second parameter is returned unaltered and the value is logged to the lib's logger:
debug(<string>, <dyn>) -> <dyn>
Examples:
debug("tag", expr) // return expr even if it is an error and logs with "tag".
func StateLib ¶
func StateLib(ctx context.Context, uid rpc.UID, conn *jsonrpc2.Connection, log *slog.Logger) cel.EnvOption
StateLib returns a cel.EnvOption to configure extended functions to allow access to the rpc kernel state store get RPC call method over the provided JSON-RPC2.0 connection.
Get State ¶
The parameter is the key to the value stored in the state store for the service configured with the UID:
get_state(<string>) -> <optional<bytes>>
Examples:
get_state("key") -> optional.of(b"value")
get_state("missing key") -> optional.none
