Struct StreamNackOptions 

pub struct StreamNackOptions { /* private fields */ }

Builder options for the xnack command.

The NACK mode is required by the server, so it is taken by StreamNackOptions::new rather than defaulted.

use redis::streams::{StreamNackMode, StreamNackOptions};

let opts = StreamNackOptions::new(StreamNackMode::Fail);

Implementations

impl StreamNackOptions

pub fn new(mode: StreamNackMode) -> Self

Create options for NACKing with the given mode.

Trait Implementations

impl Debug for StreamNackOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ToRedisArgs for StreamNackOptions

Available on crate feature streams only.

fn write_redis_args<W>(&self, out: &mut W)

where W: ?Sized + RedisWrite,

This writes the value into a vector of bytes. Each item is a single argument. Most items generate a single item.

fn to_redis_args(&self) -> Vec<Vec<u8>>

This converts the value into a vector of bytes. Each item is a single argument. Most items generate a vector of a single item.

fn describe_numeric_behavior(&self) -> NumericBehavior

Returns an information about the contained value with regards to it’s numeric behavior in a redis context. This is used in some high level concepts to switch between different implementations of redis functions (for instance INCR vs INCRBYFLOAT).

fn num_of_args(&self) -> usize

Returns the number of arguments this value will generate.
