NestedStructDegradation

Struct NestedStructDegradation 

Source
pub struct NestedStructDegradation {
    pub column: String,
    pub struct_name: String,
    pub fallback_type: &'static str,
    pub backend: String,
}
Expand description

One nested-aggregate column degrade_unsupported_nested_structs rewrote to a scalar JSON fallback because backend could not construct a real struct for it. See GeneratedCode::degraded_nested_structs for why this is surfaced at all rather than left as an internal rewrite (GH #147).

Fields§

§column: String

SQL-level name of the rewritten column (scythe_core::analyzer::AnalyzedColumn::name).

§struct_name: String

PascalCase name of the struct that could not be generated – matches [nested_struct_shape]’s decoded name, not the snake_case scythe_core::analyzer::NestedStructInfo::name it was cased from.

§fallback_type: &'static str

The neutral type the column was rewritten to: "json" or, when the manifest declares the json_array scalar and the shape was an array, "json_array".

§backend: String

[scythe_backend::manifest::BackendManifest::name] of the backend that declined the struct.
