source · [−]

pub enum RedisTtl {
    KeyDoesNotExist,
    KeyHasNoTtl,
    Ttl(usize),
}

Expand description

The result from the Redis TTL command, converting the two error codes (-1 and -2) into enum variants.

Variants

`KeyDoesNotExist`

The key requested does not exist.

`KeyHasNoTtl`

The key requested exists, but does not have a TTL.

`Ttl(usize)`

The TTL of the requested key.

Trait Implementations

impl Clone for RedisTtl

fn clone(&self) -> RedisTtl

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

impl Debug for RedisTtl

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

Formats the value using the given formatter. Read more

impl FromRedisValue for RedisTtl

fn from_redis_value(v: &Value) -> RedisResult<Self>

Given a redis Value this attempts to convert it into the given destination type. If that fails because it’s not compatible an appropriate error is generated. Read more

fn from_redis_values(items: &[Value]) -> Result<Vec<Self, Global>, RedisError>

Similar to from_redis_value but constructs a vector of objects from another vector of values. This primarily exists internally to customize the behavior for vectors of tuples. Read more

impl PartialEq<RedisTtl> for RedisTtl

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

This method tests for self and other values to be equal, and is used by ==. Read more

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

This method tests for !=.
