Enum cassandra_protocol::frame::message_result::ResResultBody

pub enum ResResultBody {
    Void,
    Rows(BodyResResultRows),
    SetKeyspace(BodyResResultSetKeyspace),
    Prepared(BodyResResultPrepared),
    SchemaChange(SchemaChange),
}

ResponseBody is a generalized enum that represents all types of responses. Each of enum option wraps related body type.

Variants

Void

Void response body. It’s an empty struct.

Rows(BodyResResultRows)

Rows response body. It represents a body of response which contains rows.

SetKeyspace(BodyResResultSetKeyspace)

Set keyspace body. It represents a body of set_keyspace query and usually contains a name of just set namespace.

Prepared(BodyResResultPrepared)

Prepared response body.

SchemaChange(SchemaChange)

Schema change body

Implementations

impl ResResultBody

pub fn into_rows(self) -> Option<Vec<Row>>

Converts body into Vec<Row> if body’s type is Row and returns None otherwise.

pub fn as_rows_metadata(&self) -> Option<&RowsMetadata>

Returns Some rows metadata if envelope result is of type rows and None otherwise

pub fn into_prepared(self) -> Option<BodyResResultPrepared>

Unwraps body and returns BodyResResultPrepared which contains an exact result of PREPARE query.

pub fn into_set_keyspace(self) -> Option<BodyResResultSetKeyspace>

Unwraps body and returns BodyResResultSetKeyspace which contains an exact result of use keyspace query.

impl ResResultBody

pub fn from_cursor(
    cursor: &mut Cursor<&[u8]>,
    version: Version
) -> Result<ResResultBody>

Trait Implementations

impl Clone for ResResultBody

fn clone(&self) -> ResResultBody

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResResultBody

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

Formats the value using the given formatter.

impl Hash for ResResultBody

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,

Feeds a slice of this type into the given Hasher.

impl Ord for ResResultBody

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<ResResultBody> for ResResultBody

fn eq(&self, other: &ResResultBody) -> 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<ResResultBody> for ResResultBody

fn partial_cmp(&self, other: &ResResultBody) -> 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 ResResultBody

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.
