Enum TypeCode 

pub enum TypeCode {
    Unspecified = 0,
    Bool = 1,
    Int64 = 2,
    Float64 = 3,
    Timestamp = 4,
    Date = 5,
    String = 6,
    Bytes = 7,
    Array = 8,
    Struct = 9,
}

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".

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].

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>

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

Trait Implementations

impl Clone for TypeCode

fn clone(&self) -> TypeCode

Returns a duplicate 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,

Restrict a value to a certain interval.

impl PartialEq for TypeCode

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

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.
