Trait FromSql

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

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

Required Methods

fn column_result(value: ValueRef<'_>) -> FromSqlResult<Self>

Converts SQLite value into Rust value.

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.

Implementations on Foreign Types

impl FromSql for Value

Available on crate feature serde_json only.

Deserialize SQLite value to JSON Value:
