Struct TypeMapper 

pub struct TypeMapper { /* private fields */ }

Implementations

impl TypeMapper

pub fn new(config: TypeMappingConfig) -> Self

pub fn used_features(&self) -> UsedFeatures

Snapshot of typed-scalar crates this mapper has referenced.

pub fn config(&self) -> &TypeMappingConfig

Borrow the underlying type-mapping config — useful for non-format-mapping toggles (shape, enums, constraints) that other modules need to inspect.

pub fn config_shape_primitive_unions(&self) -> Option<bool>

Q2.7 helper: should anyOf of primitives become an untagged enum with primitive variant types directly (true), or fall back to the pre-Q2.7 type-alias-per-variant shape (false)? Default: true.

pub fn config_shape_additional_properties_typed(&self) -> Option<bool>

Q2.3 helper: should additionalProperties: <schema> produce BTreeMap<String, T> (true) or degrade to BTreeMap<String, serde_json::Value> (false)? Default: true.

pub fn config_constraint_mode(&self) -> ConstraintMode

Q2.4 helper: which constraint-annotation mode is active? Defaults to ConstraintMode::Doc when the [generator.types.constraints] block is absent or its mode field is unset.

pub fn string_format(&self, format: Option<&str>) -> MappedType

Map string + optional format → typed Rust scalar.

Routing:

1. Apply user-provided + built-in format_aliases.
2. Dispatch on the normalized format.
3. Honor each format’s strategy in self.config.
4. Record any introduced crate in used_features.

pub fn integer_format(&self, format: Option<&str>) -> MappedType

Map integer + optional format → Rust type.

Q2.1: honors uint32 / uint64 (and a few vendor variants like uint) when config.unsigned is true (default). Setting unsigned = false reverts to the pre-Q2.1 behavior where unsigned formats degrade to i64.

pub fn number_format(&self, format: Option<&str>) -> MappedType

Map number + optional format → Rust type.

format: float maps to f64 by default rather than f32. JSON has no binary32: a value written on the wire as 0.03 parses losslessly into f64, but through f32 it becomes 0.029999999329447746. The declared format describes the server’s internal storage, not the transport, so f32 discards precision the response actually carried. Observed live on RunPod’s catalog prices, which declare float while the billing endpoints declare double.

Set float_precision = "f32" under [generator.types] to map strictly by declared format instead.

pub fn boolean(&self) -> MappedType

pub fn untyped_array(&self) -> MappedType

pub fn dynamic_json(&self) -> MappedType

pub fn null_unit(&self) -> MappedType

pub fn map(&self, ty: OpenApiSchemaType, details: &SchemaDetails) -> MappedType

One-shot dispatch from (OpenApiSchemaType, &SchemaDetails).

Trait Implementations

impl Default for TypeMapper

fn default() -> Self

Returns the “default value” for a type.
