Struct cassandra_protocol::frame::frame_error::ReadFailureError

pub struct ReadFailureError {
    pub cl: Consistency,
    pub received: CInt,
    pub block_for: CInt,
    pub num_failures: CInt,
    // some fields omitted
}

A non-timeout exception during a read request.

Fields

cl: Consistency

Consistency level of query.

received: CInt

i32 representing the number of nodes having acknowledged the request.

block_for: CInt

i32 representing the number of replicas whose acknowledgement is required to achieve cl.

num_failures: CInt

Represents the number of nodes that experience a failure while executing the request.

Implementations

impl ReadFailureError

pub fn replica_has_responded(&self) -> bool

Shows if replica has responded to a query.

Trait Implementations

impl Clone for ReadFailureError

fn clone(&self) -> ReadFailureError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReadFailureError

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

Formats the value using the given formatter.

impl FromCursor for ReadFailureError

fn from_cursor(cursor: &mut Cursor<&[u8]>) -> Result<ReadFailureError>

It should return an implementor from an io::Cursor over an array of bytes.

impl Hash for ReadFailureError

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 ReadFailureError

fn cmp(&self, other: &ReadFailureError) -> 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) -> Self

Restrict a value to a certain interval.

impl PartialEq<ReadFailureError> for ReadFailureError

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

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

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

This method tests for !=.

impl PartialOrd<ReadFailureError> for ReadFailureError

fn partial_cmp(&self, other: &ReadFailureError) -> 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.
