TypeCode is used as part of [Type][google.spanner.v1.Type] to indicate the type of a Cloud Spanner value.

Each legal value of a type can be encoded to or decoded from a JSON value, using the encodings described below. All Cloud Spanner values can be null, regardless of type; nulls are always encoded as a JSON null.

Variants

Unspecified = 0

Not specified.

Bool = 1

Encoded as JSON true or false.

Int64 = 2

Encoded as string, in decimal format.

Float64 = 3

Encoded as number, or the strings "NaN", "Infinity", or "-Infinity".

Float32 = 15

Encoded as number, or the strings "NaN", "Infinity", or "-Infinity".

Timestamp = 4

Encoded as string in RFC 3339 timestamp format. The time zone must be present, and must be "Z".

If the schema has the column option allow_commit_timestamp=true, the placeholder string "spanner.commit_timestamp()" can be used to instruct the system to insert the commit timestamp associated with the transaction commit.

Date = 5

Encoded as string in RFC 3339 date format.

String = 6

Encoded as string.

Bytes = 7

Encoded as a base64-encoded string, as described in RFC 4648, section 4.

Array = 8

Encoded as list, where the list elements are represented according to [array_element_type][google.spanner.v1.Type.array_element_type].

Struct = 9

Encoded as list, where list element i is represented according to [struct_type.fields[i]][google.spanner.v1.StructType.fields].

Numeric = 10

Encoded as string, in decimal format or scientific notation format.
Decimal format:
\[+-\]Digits\[.[Digits]\] or
[+-][Digits].Digits

Scientific notation:
\[+-\]Digits\[.[Digits\]][ExponentIndicator\[+-\]Digits] or
[+-][Digits].Digits\[ExponentIndicator[+-\]Digits]
(ExponentIndicator is "e" or "E")

Json = 11

Encoded as a JSON-formatted string as described in RFC 7159. The following rules are applied when parsing JSON input:

• Whitespace characters are not preserved.
• If a JSON object has duplicate keys, only the first key is preserved.
• Members of a JSON object are not guaranteed to have their order preserved.
• JSON array elements will have their order preserved.

Proto = 13

Encoded as a base64-encoded string, as described in RFC 4648, section 4.

Enum = 14

Encoded as string, in decimal format.

Implementations

impl TypeCode

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of TypeCode.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl TypeCode

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 TypeCode

fn clone(&self) -> TypeCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeCode

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

Formats the value using the given formatter.

impl Default for TypeCode

fn default() -> TypeCode

Returns the “default value” for a type.

impl From<TypeCode> for i32

fn from(value: TypeCode) -> i32

Converts to this type from the input type.

impl Hash for TypeCode

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 TypeCode

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

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

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

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<TypeCode, DecodeError>

Performs the conversion.

impl Copy for TypeCode

impl Eq for TypeCode

impl StructuralPartialEq for TypeCode
