impl<T> From<T> for T

const: unstable · source§

fn from(t: T) -> T

Returns the argument unchanged.

source§

impl<T, U> Into<U> for Twhere U: From<T>,

const: unstable · source§

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source§

impl<F> ModelQueryFilterExt for Fwhere F: ModelQueryFilter,

source§

fn and<F1>(self, filter: F1) -> ModelQueryFilterAnd<F, F1>where F1: ModelQueryFilter,

Combine two filters with an AND operator

Example
User::select().filter(User::name.eq("John").and(User::age.gt(18))).exec(conn);

This will generate the following SQL query:

SELECT * FROM users WHERE users.name = ? AND users.age > ?;
Note

This is not a beautiful way to write this query, so you should use ‘&’ instead:

User::select().filter(User::name.eq("John") & User::age.gt(18)).exec(conn);
source§

fn or<F1>(self, filter: F1) -> ModelQueryFilterOr<F, F1>where F1: ModelQueryFilter,

Combine two filters with an OR operator

Example
User::select().filter(User::name.eq("John").or(User::age.gt(18))).exec(conn);

This will generate the following SQL query:

SELECT * FROM users WHERE users.name = ? OR users.age > ?;
Note

This is not a beautiful way to write this query, so you should use ‘|’ instead:

User::select().filter(User::name.eq("John") | User::age.gt(18)).exec(conn);
