Trait ArrayElement 

pub trait ArrayElement: Sized {
    type ArrayValueType: ArrayValue;

    // Required methods
    fn into_array_value(self) -> Self::ArrayValueType;
    fn try_from_value(v: Value) -> Result<Vec<Option<Self>>, ValueTypeErr>;
}

Available on crate feature postgres-array only.

Trait for custom types that can be used as PostgreSQL array elements.

When implemented, SeaQuery will provide:

• ValueType for Vec<T> and Vec<Option<T>>
• From<Vec<T>> for Value / From<Vec<Option<T>>> for Value
• From<Vec<T>> for Array / From<Vec<Option<T>>> for Array

Required Associated Types

type ArrayValueType: ArrayValue

The underlying element type stored in the array.

Usually this is a built-in type like String, i32, Uuid, …

Required Methods

fn into_array_value(self) -> Self::ArrayValueType

Convert self into the underlying array element type.

fn try_from_value(v: Value) -> Result<Vec<Option<Self>>, ValueTypeErr>

Convert from a Value to Vec<Option<Self>>

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.
