Enum RosPrimitive 

pub enum RosPrimitive {
    Bool,
    Byte,
    Char,
    Int8,
    Uint8,
    Int16,
    Uint16,
    Int32,
    Uint32,
    Int64,
    Uint64,
    Float32,
    Float64,
    String,
    Wstring,
}

Strongly-typed enum of every ROS2 IDL primitive. This is the single source of truth for how a primitive maps to wire formats across generators. Both proto_gen and mcp_python_gen consume the methods on this enum so a new primitive only has to be added here once.

The catch-all silent fallbacks that used to live in each generator (_ => "int", _ => "bytes") are gone — every primitive must be listed explicitly. An unrecognised type now panics at codegen time instead of silently producing the wrong wire shape.

Implementations

impl RosPrimitive

pub fn parse(s: &str) -> Option<Self>

pub fn as_ros_str(&self) -> &'static str

pub fn proto_type(&self) -> &'static str

proto3 wire type for this primitive.

pub fn python_type(&self) -> &'static str

Python type name used in MCP dataclass annotations.

pub fn python_default(&self) -> &'static str

Default literal in Python for a non-array field.

pub fn python_cast(&self) -> &'static str

Python cast invoked by from_dict() when validating an inbound JSON value. Same as the type name for builtin casts.

pub fn json_schema_type(&self) -> &'static str

JSON Schema base type (“integer” / “number” / “boolean” / “string”).

pub fn integer_range(&self) -> Option<(i128, i128)>

Inclusive range constraint for integer primitives (used by from_dict validation and JSON Schema minimum/maximum). Floats / strings / bool return None — JSON Schema’s defaults already cover them.

pub fn is_blob_element(&self) -> bool

True if this primitive is the canonical “raw byte buffer” type. Only uint8 qualifies — byte is signed 8-bit and shouldn’t be conflated. Used by both proto and MCP gens to decide whether a T[] field becomes a wire-level byte blob (bytes in proto, base64-encoded bytes in MCP).

Trait Implementations

impl Clone for RosPrimitive

fn clone(&self) -> RosPrimitive

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RosPrimitive

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

Formats the value using the given formatter.

impl Hash for RosPrimitive

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RosPrimitive

fn eq(&self, other: &RosPrimitive) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
