Trait grafana_plugin_sdk::data::IntoFieldType

pub trait IntoFieldType {
    type ElementType;

    const TYPE_INFO_TYPE: TypeInfoType;

    // Required method
    fn into_field_type(self) -> Option<Self::ElementType>;
}

Indicates that a type can be converted to one that is FieldType, and holds associated metadata.

For example, DateTime<T>s are valid Field values, but must first be converted to nanoseconds-since-the-epoch in i64 values; the original type and corresponding TypeInfoType is stored here.

This trait mainly exists to enable smoother APIs when creating Fields.

Required Associated Types

type ElementType

The type to which Self will be converted when storing values in a Field.

Required Associated Constants

const TYPE_INFO_TYPE: TypeInfoType

The corresponding TypeInfoType for this original data type.

Required Methods

fn into_field_type(self) -> Option<Self::ElementType>

Convert this type into an (optional) field type.

Object Safety

This trait is not object safe.
