Trait Attribute

pub trait Attribute: Sized {
    // Required methods
    fn into_attr(self) -> AttributeValue;
    fn from_attr(value: AttributeValue) -> Result<Self, AttributeError>;
}

A type capable of being converted into an or from and AWS AttributeValue

Default implementations of this are provided for each type of AttributeValue field which map to naturally fitting native Rustlang types.

Examples

use dynomite::{dynamodb::AttributeValue, Attribute};

assert_eq!(
    "test".to_string().into_attr().s,
    AttributeValue {
        s: Some("test".to_string()),
        ..AttributeValue::default()
    }
    .s
);

Required Methods

fn into_attr(self) -> AttributeValue

Returns a conversion into an AttributeValue

fn from_attr(value: AttributeValue) -> Result<Self, AttributeError>

Returns a fallible conversion from an AttributeValue

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
