Struct StructDestructure 

Source 
pub struct StructDestructure<'db> {
    pub input: VarUsage<'db>,
    pub var_reqs: Vec<VarRequest<'db>>,
}
Expand description

Generator for StatementStructDestructure.

Note that we return Vec<VariableId> rather than Vec<VarUsage> as the caller typically has a more accurate location than the one we have in the var requests.

Fields§

§input: VarUsage<'db>

Variable that holds the struct value.

§var_reqs: Vec<VarRequest<'db>>

Variable requests for the newly generated member values.
