Struct ComputedDescriptor 

pub struct ComputedDescriptor {
    pub name: String,
    pub expression: String,
    pub return_type: Option<String>,
    pub link_target: Option<String>,
    pub link_multi: bool,
}

Fields

name: String

expression: String

PyQL expression evaluated at query time.

return_type: Option<String>

PostgreSQL return type, if known at schema-build time.

link_target: Option<String>

The qualified object type a link-valued computed selects (Computed[Link[Email], "…"]) — None for a scalar computed, whose type is return_type instead. A consumer that has only the schema to go on (the schema browser, an editor) cannot tell the two apart otherwise: both carry a bare expression string.

link_multi: bool

Whether that link-valued computed selects many.
