Trait DecodeSelectedRef 

pub trait DecodeSelectedRef<RowRef, R> {
    // Required method
    fn decode(row: RowRef) -> Result<R, DrizzleError>;
}

Marker-directed row decoding for .all()/.get().

Required Methods

fn decode(row: RowRef) -> Result<R, DrizzleError>

Decode the row into R according to the marker.

Errors

Returns an error if the row cannot be decoded into the expected type (missing columns, type mismatch, or downstream conversion failure).

Dyn Compatibility

This trait is not dyn compatible.

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