Enum SchemaChangeOptions

#[non_exhaustive]
pub enum SchemaChangeOptions {
    Keyspace(String),
    TableType(String, String),
    FunctionAggregate(String, String, Vec<String>),
}

Information about changes made.

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.

Keyspace(String)

Changes related to keyspaces. Contains keyspace name.

TableType(String, String)

Changes related to tables. Contains keyspace and table names.

FunctionAggregate(String, String, Vec<String>)

Changes related to functions and aggregations. Contains:

• keyspace containing the user defined function/aggregate
• the function/aggregate name
• list of strings, one string for each argument type (as CQL type)

Trait Implementations

impl Clone for SchemaChangeOptions

fn clone(&self) -> SchemaChangeOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaChangeOptions

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

Formats the value using the given formatter.

impl Hash for SchemaChangeOptions

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 SchemaChangeOptions

fn cmp(&self, other: &SchemaChangeOptions) -> 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,

Restrict a value to a certain interval.

impl PartialEq for SchemaChangeOptions

fn eq(&self, other: &SchemaChangeOptions) -> 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 PartialOrd for SchemaChangeOptions

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for SchemaChangeOptions

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.
