Implementations

impl Resp3Value

pub fn as_string(&self) -> RedisResult<String>

Convert to a string if possible

Errors

Returns an error if the value cannot be converted to a string.

pub fn as_int(&self) -> RedisResult<i64>

Convert to an integer if possible

Errors

Returns an error if the value cannot be converted to an integer.

pub fn as_float(&self) -> RedisResult<f64>

Convert to a float if possible

Errors

Returns an error if the value cannot be converted to a float.

pub fn as_bool(&self) -> RedisResult<bool>

Convert to a boolean if possible

Errors

Returns an error if the value cannot be converted to a boolean.

pub const fn is_null(&self) -> bool

Check if the value is null

pub const fn type_name(&self) -> &'static str

Get the type name of the value

Trait Implementations

impl Clone for Resp3Value

fn clone(&self) -> Resp3Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Resp3Value

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

Formats the value using the given formatter.

impl From<Resp3Value> for RespValue

Convert RESP3 value to RESP2 value for backward compatibility

fn from(value: Resp3Value) -> Self

Converts to this type from the input type.

impl From<RespValue> for Resp3Value

Convert RESP2 value to RESP3 value

fn from(value: RespValue) -> Self

Converts to this type from the input type.

impl Hash for Resp3Value

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Resp3Value

fn eq(&self, other: &Resp3Value) -> 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.
