Struct GeneratedCode 

#[non_exhaustive]
pub struct GeneratedCode {
    pub query_fn: Option<String>,
    pub row_struct: Option<String>,
    pub model_struct: Option<String>,
    pub enum_def: Option<String>,
    pub nested_struct_defs: Vec<NestedStructDef>,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

query_fn: Option<String>

row_struct: Option<String>

model_struct: Option<String>

enum_def: Option<String>

nested_struct_defs: Vec<NestedStructDef>

Nested-aggregate struct definitions this query needs, one entry per scythe_core::analyzer::NestedStructInfo the backend opted into.

Kept out of model_struct (where composites go) because these have to be deduplicated across the queries written into one file: two queries can legitimately derive the same struct name, and emitting the definition twice is E0428 in Rust and a redeclaration in every other target. model_struct is already a rendered blob with no identity attached, so the name has to survive alongside the code for the writer to dedupe on. See scythe-cli’s generate_for_backend.

Implementations

impl GeneratedCode

pub fn build(init: impl FnOnce(&mut Self)) -> Self

Build a GeneratedCode from Default, assigning fields inside init.

#[non_exhaustive] forbids a struct literal outside this crate – including with ..Default::default() – so downstream crates (scythe-cli, and anyone embedding the generator) have no other way to construct one. Mirrors scythe_core::analyzer::AnalyzedQuery::build, and keeping construction a single expression avoids clippy’s field_reassign_with_default.

use scythe_codegen::GeneratedCode;

let code = GeneratedCode::build(|c| {
    c.query_fn = Some("fn get_user() {}".to_string());
});
assert!(code.row_struct.is_none());

Trait Implementations

impl Clone for GeneratedCode

fn clone(&self) -> GeneratedCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GeneratedCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GeneratedCode

fn default() -> GeneratedCode

Returns the “default value” for a type.
