Implementations

source

impl TypeAlterOpt

source

pub fn before<T>(self, value: T) -> Self where
T: IntoIden,

Changes only ADD VALUE x options into ADD VALUE x BEFORE options, does nothing otherwise

source

pub fn after<T>(self, value: T) -> Self where
T: IntoIden,

Changes only ADD VALUE x options into ADD VALUE x AFTER options, does nothing otherwise
