Enum StreamMaxlen

pub enum StreamMaxlen {
    Equals(usize),
    Approx(usize),
}

Utility enum for passing MAXLEN [= or ~] [COUNT] arguments into StreamCommands. The enum value represents the count.

Variants

Equals(usize)

Match an exact count

Approx(usize)

Match an approximate count

Trait Implementations

impl Clone for StreamMaxlen

fn clone(&self) -> StreamMaxlen

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StreamMaxlen

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

Formats the value using the given formatter.

impl PartialEq for StreamMaxlen

fn eq(&self, other: &StreamMaxlen) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToRedisArgs for StreamMaxlen

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.
