PERSIST key

Client:

persist(
    name: KeyT
) → int

PERSIST(
    key: RedisArgument
) → Any

persist(
    key: byte[]
) → long  // 1 if the timeout was removed, 0 if key does not exist or does not have an associated timeout

persist(
    key: String
) → long  // 1 if the timeout was removed, 0 if key does not exist or does not have an associated timeout

persist(
    key: K  // the key.
) → Boolean  // Boolean integer-reply specifically: true if the timeout was removed. false if key does not exist or does not have an associated timeout.

persist(
    key: K  // the key.
) → RedisFuture<Boolean>  // Boolean integer-reply specifically: true if the timeout was removed. false if key does not exist or does not have an associated timeout.

persist(
    key: K  // the key.
) → Mono<Boolean>  // Boolean integer-reply specifically: true if the timeout was removed. false if key does not exist or does not have an associated timeout.

Persist(
    ctx: context.Context,
    key: string
) → *BoolCmd

KeyPersist(
    key: RedisKey,  // The key to persist.
    flags: CommandFlags  // The flags to use for this operation.
) → bool  // true if the timeout was removed. false if key does not exist or does not have an associated timeout.

KeyPersistAsync(
    key: RedisKey,  // The key to persist.
    flags: CommandFlags  // The flags to use for this operation.
) → Task<bool>  // true if the timeout was removed. false if key does not exist or does not have an associated timeout.

persist(
    $key: string
) → int
