Derive Macro DeriveArrowSchema 

#[derive(DeriveArrowSchema)]
{
    // Attributes available to this derive:
    #[sea_orm]
}

Available on crate feature macros only.

The DeriveArrowSchema derive macro generates an arrow_schema() method that returns an Apache Arrow schema from a SeaORM entity definition.

This macro is automatically applied when #[sea_orm(arrow_schema)] is specified on a model. You typically don’t need to use this derive macro directly.

Usage

use sea_orm::entity::prelude::*;

#[sea_orm::model]
#[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
#[sea_orm(table_name = "user", arrow_schema)]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i64,
    pub name: String,
    #[sea_orm(column_type = "Decimal(Some((20, 4)))")]
    pub amount: Decimal,
}
