Struct StateOpResult 

pub struct StateOpResult {
    pub found: bool,
    pub value: Option<Vec<u8>>,
    pub version: Option<u64>,
    pub keys: Option<Vec<String>>,
    pub error: Option<String>,
}

Result of a state operation.

Fields

found: bool

Whether the key was found (for Get) or operation succeeded.

value: Option<Vec<u8>>

Returned value bytes (for Get).

version: Option<u64>

Current version / etag if the backend supports it.

keys: Option<Vec<String>>

Matched keys for List operations.

error: Option<String>

Error message if the operation failed.

Implementations

impl StateOpResult

pub fn found(value: Vec<u8>) -> Self

A successful result with a value.

pub fn not_found() -> Self

A not-found result.

pub fn ok() -> Self

A successful write/delete acknowledgement.

pub fn list(keys: Vec<String>) -> Self

A list result.

pub fn err(message: impl Into<String>) -> Self

An error result.

pub fn with_version(self, version: u64) -> Self

Sets the version on this result.

Trait Implementations

impl Clone for StateOpResult

fn clone(&self) -> StateOpResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateOpResult

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StateOpResult

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StateOpResult

fn eq(&self, other: &StateOpResult) -> 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 Serialize for StateOpResult

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
