Trait FromRow

pub trait FromRow: Sized {
    // Required method
    fn from_row(row: Row) -> Result<Self, FromRowError>;
}

This trait defines a way to convert CQL Row into some rust type

Required Methods

fn from_row(row: Row) -> Result<Self, FromRowError>

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.
