Trait diesel::prelude::QueryableByName

source ·
pub trait QueryableByName<DB>
where Self: Sized, DB: Backend,
{ // Required method fn build<'a>(row: &impl NamedRow<'a, DB>) -> Result<Self>; }
Expand description

Deserializes the result of a query constructed with sql_query.

This trait can be derived

§Examples

If we just want to map a query to our struct, we can use derive.

#[derive(QueryableByName, PartialEq, Debug)]
struct User {
    id: i32,
    name: String,
}

let first_user = sql_query("SELECT * FROM users ORDER BY id LIMIT 1")
    .get_result(connection)?;
let expected = User { id: 1, name: "Sean".into() };
assert_eq!(expected, first_user);

If we want to do additional work during deserialization, we can use deserialize_as to use a different implementation.

struct LowercaseString(String);

impl Into<String> for LowercaseString {
    fn into(self) -> String {
        self.0
    }
}

impl<DB, ST> FromSql<ST, DB> for LowercaseString
where
    DB: Backend,
    String: FromSql<ST, DB>,
{
    fn from_sql(bytes: DB::RawValue<'_>) -> deserialize::Result<Self> {
        String::from_sql(bytes)
            .map(|s| LowercaseString(s.to_lowercase()))
    }
}

#[derive(QueryableByName, PartialEq, Debug)]
struct User {
    id: i32,
    #[diesel(deserialize_as = LowercaseString)]
    name: String,
}

let first_user = sql_query("SELECT * FROM users ORDER BY id LIMIT 1")
    .get_result(connection)?;
let expected = User { id: 1, name: "sean".into() };
assert_eq!(expected, first_user);

Required Methods§
