Enum cassandra_protocol::frame::message_result::ResultKind

#[non_exhaustive]
pub enum ResultKind {
    Void,
    Rows,
    SetKeyspace,
    Prepared,
    SchemaChange,
}

ResultKind is enum which represents types of result.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Void

Void result.

Rows

Rows result.

SetKeyspace

Set keyspace result.

Prepared

Prepared result.

SchemaChange

Schema change result.

Trait Implementations

impl Clone for ResultKind

fn clone(&self) -> ResultKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResultKind

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

Formats the value using the given formatter.

impl Display for ResultKind

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

Formats the value using the given formatter.

impl From<ResultKind> for CInt

fn from(value: ResultKind) -> Self

Converts to this type from the input type.

impl FromBytes for ResultKind

fn from_bytes(bytes: &[u8]) -> Result<ResultKind>

It gets and array of bytes and should return an implementor struct.

impl FromCursor for ResultKind

fn from_cursor( cursor: &mut Cursor<&[u8]>, _version: Version ) -> Result<ResultKind>

Tries to parse Self from a cursor of bytes.

impl Hash for ResultKind

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 Ord for ResultKind

fn cmp(&self, other: &ResultKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ResultKind

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

impl PartialOrd for ResultKind

fn partial_cmp(&self, other: &ResultKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ResultKind

fn serialize(&self, cursor: &mut Cursor<&mut Vec<u8>>, version: Version)

Serializes given value using the cursor.

fn serialize_to_vec(&self, version: Version) -> Vec<u8>

Wrapper for easily starting hierarchical serialization.

impl TryFrom<i32> for ResultKind

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: CInt) -> Result<Self, Self::Error>

Performs the conversion.
