Trait ic_sqlite_features::types::FromSql

pub trait FromSql: Sized {
    // Required method
    fn column_result(value: ValueRef<'_>) -> Result<Self, FromSqlError>;
}

A trait for types that can be created from a SQLite value.

Required Methods

fn column_result(value: ValueRef<'_>) -> Result<Self, FromSqlError>

Converts SQLite value into Rust value.

Object Safety

This trait is not object safe.
