Trait FromValues 

pub trait FromValues: Sized {
    // Required method
    fn from_values(row: &Row) -> Result<Self, QueryError>;
}

A type decoded from the columns of a row by position: a single DbType for one column, or a tuple of up to six.

let rows: Vec<(String, i64)> = Book::objects(&db)
    .values_list([Book::title.select(), Book::likes.select()])
    .await?;

Required Methods

fn from_values(row: &Row) -> Result<Self, QueryError>

Decode row.

Errors

QueryError::Decode if a column is missing or has the wrong type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
