pub struct ScanOptions { /* private fields */ }
Expand description
Options for the SCAN command
§Example
use redis::{Commands, RedisResult, ScanOptions, Iter};
fn force_fetching_every_matching_key<'a, T: redis::FromRedisValue>(
con: &'a mut redis::Connection,
pattern: &'a str,
count: usize,
) -> RedisResult<Iter<'a, T>> {
let opts = ScanOptions::default()
.with_pattern(pattern)
.with_count(count);
con.scan_options(opts)
}

fn default() -> ScanOptions
Returns the “default value” for a type. Read more

Source§fn write_redis_args<W>(&self, out: &mut W)where
W: ?Sized + RedisWrite,
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. Read more
Source§fn num_of_args(&self) -> usize
fn num_of_args(&self) -> usize
Returns the number of arguments this value will generate. Read more
Source§fn to_redis_args(&self) -> Vec<Vec<u8>>
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. Read more
Source§fn describe_numeric_behavior(&self) -> NumericBehavior
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
).Auto Trait Implementations§
