Struct oasis_core_runtime::storage::mkvs::LogEntry

pub struct LogEntry {
    pub key: Vec<u8>,
    pub value: Option<Vec<u8>>,
}

An entry in the write log, describing a single update.

Fields

key: Vec<u8>

The key that was inserted or deleted.

value: Option<Vec<u8>>

The inserted value (empty if the key was deleted).

Implementations

impl LogEntry

pub fn new(key: &[u8], value: &[u8]) -> Self

pub fn kind(&self) -> LogEntryKind

Trait Implementations

impl Clone for LogEntry

fn clone(&self) -> LogEntry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LogEntry

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

Formats the value using the given formatter.

impl Decode for LogEntry

fn try_default() -> Result<Self, DecodeError>

Try to decode from a missing/null/undefined value.

fn try_from_cbor_value(value: Value) -> Result<Self, DecodeError>

Try to decode from a given CBOR value.

fn try_from_cbor_value_default(value: Value) -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a given CBOR value, calling try_default in case the value is null or undefined.

impl Default for LogEntry

fn default() -> LogEntry

Returns the “default value” for a type.

impl Encode for LogEntry

fn into_cbor_value(self) -> Value

Encode the type into a CBOR Value.

fn is_empty(&self) -> bool

Whether the value is equal to the empty value for the type.

impl Hash for LogEntry

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 LogEntry

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

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

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

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