Trait FromCqlVal

pub trait FromCqlVal<T>: Sized {
    // Required method
    fn from_cql(cql_val: T) -> Result<Self, FromCqlValError>;
}

This trait defines a way to convert CqlValue or Option<CqlValue> into some rust type

Required Methods

fn from_cql(cql_val: T) -> Result<Self, FromCqlValError>

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.
