Implementations

impl RespValue

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_bytes(&self) -> RedisResult<Bytes>

Convert to bytes if possible

Errors

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

pub fn as_array(&self) -> RedisResult<Vec<Self>>

Convert to an array if possible

Errors

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

pub const fn is_null(&self) -> bool

Check if this is a null value

pub const fn is_error(&self) -> bool

Check if this is an error

pub fn into_error(self) -> Option<String>

Extract error message if this is an error

Trait Implementations

impl Clone for RespValue

fn clone(&self) -> RespValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RespValue

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

Formats the value using the given formatter.

impl From<&str> for RespValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Bytes> for RespValue

fn from(b: Bytes) -> Self

Converts to this type from the input type.

impl From<String> for RespValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for RespValue

fn from(b: Vec<u8>) -> Self

Converts to this type from the input type.

impl From<i64> for RespValue

fn from(i: i64) -> Self

impl PartialEq for RespValue

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