Enum TableExistsOption

#[repr(i32)]
pub enum TableExistsOption {
    Unspecified = 0,
    Fail = 1,
    Append = 2,
    Replace = 3,
}

The action to take if the target table already exists

Variants

Unspecified = 0

Do not use. Servers should error if this is specified by a client.

Fail = 1

Fail if the table already exists

Append = 2

Append to the table if it already exists

Replace = 3

Drop and recreate the table if it already exists

Implementations

impl TableExistsOption

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of TableExistsOption.

pub fn from_i32(value: i32) -> Option<TableExistsOption>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a TableExistsOption, or None if value is not a valid variant.

impl TableExistsOption

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for TableExistsOption

fn clone(&self) -> TableExistsOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableExistsOption

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

Formats the value using the given formatter.

impl Default for TableExistsOption

fn default() -> TableExistsOption

Returns the “default value” for a type.

impl From<TableExistsOption> for i32

fn from(value: TableExistsOption) -> i32

Converts to this type from the input type.

impl Hash for TableExistsOption

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 TableExistsOption

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

fn eq(&self, other: &TableExistsOption) -> 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 TableExistsOption

fn partial_cmp(&self, other: &TableExistsOption) -> 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 TryFrom<i32> for TableExistsOption

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<TableExistsOption, UnknownEnumValue>

Performs the conversion.
