Expand description

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>

👎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.
