Struct FieldSchema

pub struct FieldSchema {
    pub name: String,
    pub source: FieldSource,
    pub ty: FieldType,
}

The name and type information for a field of a timeseries schema.

Fields

name: String

source: FieldSource

The source from which a field is derived, the target or metric.

ty: FieldType

The FieldType identifies the data type of a target or metric field.

Trait Implementations

impl Clone for FieldSchema

fn clone(&self) -> FieldSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldSchema

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

Formats the value using the given formatter.

impl Default for FieldSchema

fn default() -> FieldSchema

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FieldSchema

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for FieldSchema

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for FieldSchema

fn eq(&self, other: &FieldSchema) -> 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 Serialize for FieldSchema

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Tabled for FieldSchema

const LENGTH: usize = 3usize

A length of fields and headers, which must be the same.

fn fields(&self) -> Vec<String>

Fields method must return a list of cells.

fn headers() -> Vec<String>

Headers must return a list of column names.
