Trait FromRow

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

👎Deprecated since 0.15.0: Legacy deserialization API is inefficient and is going to be removed soon

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

Required Methods

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

👎Deprecated since 0.15.0: Legacy deserialization API is inefficient and is going to be removed soon

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.
