Struct ScalarProjection 

pub struct ScalarProjection {
    pub sql: Cow<'static, str>,
    pub params: Vec<FilterValue>,
    pub alias: &'static str,
}

A scalar-subquery projection added to a SELECT clause, emitted as (<sql>) AS <alias>. The alias is a codegen-controlled &'static str — never user input — so it can be safely interpolated into SQL after identifier quoting.

Fields

sql: Cow<'static, str>

SQL fragment with {N} placeholders.

params: Vec<FilterValue>

Parameter values referenced by the {N} placeholders.

alias: &'static str

Output column alias.

Implementations

impl ScalarProjection

pub fn new( sql: impl Into<Cow<'static, str>>, params: Vec<FilterValue>, alias: &'static str, ) -> Self
