Increments the number stored at field in the hash stored at key by given delta. If the field does not exist, it is set to 0 before performing the operation.

hincrbyfloat

Source

Float hincrbyfloat(Str key, Str field, Float delta)

Increment the string representing a floating point number stored at field in the hash stored at key by the specified delta. If the key does not exist, it is set to 0 before performing the operation.

hmget

Source

Str?[] hmget(Str key, Str[] fields)

Get the hash field for given key.

hmset

Source

Void hmset(Str key, Str:Obj vals)

Set all hash values in vals for given key.

host

Source

const Str host

Host name of Redis server.

hset

Source

Void hset(Str key, Str field, Obj val)

Set the hash field to the given value for key.

incr

Source

Int incr(Str key, Duration? px := null)

Increments the number stored at key by one. If the key does not exist, it is set to 0 before performing the operation. If px is non-null expire this key after the given timeout in milliseconds. Returns the value of the key after the increment.

incrby

Source

Int incrby(Str key, Int delta, Duration? px := null)

Increments the number stored at key by delta. If the key does not exist, it is set to 0 before performing the operation. If px is non-null expire this key after the given timeout in milliseconds. Returns the value of the key after the increment.

incrbyfloat

Source

Float incrbyfloat(Str key, Float delta, Duration? px := null)

Increment the string representing a floating point number stored at key by the specified delta. If the key does not exist, it is set to 0 before performing the operation. If px is non-null expire this key after the given timeout in milliseconds. Returns the value of the key after the increment.

invoke

Source

Obj? invoke(Obj[] args)

Invoke the given command and return response.

make

Source

new make(Str host, Int port := 6379)

Create a new client instance for given host and port.

memStats

Source

Str:Obj memStats()

Returns information about the memory usage of server.

pexpire

Source

Void pexpire(Str key, Duration milliseconds)

Expire given key after given ms has elasped, where timeout must be in even millisecond intervals.

pipeline

Source

Obj?[] pipeline(Obj[] invokes)

Pipeline multiple invoke requests and return batched results.

port

Source

const Int port

Port number of Redis server.

set

Source

Void set(Str key, Obj? val, Duration? px := null)

Set the given key to value, if val is null this method deletes the given key (see del). If px is non-null expire this key after the given timeout in milliseconds.

setnx

Source

Bool setnx(Str key, Obj val, Duration? px := null)

Set the given key to value only if key does not exist. Returns true if set was succesfull, or false if set failed due to already existing key. If px is non-null expire this key after the given timeout in milliseconds.
