Enum PtxParam 

pub enum PtxParam {
    Scalar {
        name: String,
        ptx_type: PtxType,
    },
    Pointer {
        name: String,
        elem_type: PtxType,
    },
}

A parameter to a PTX kernel function.

In PTX, kernel parameters are declared in the .entry signature:

• Scalar: .param .u32 n — a value passed by copy
• Pointer: .param .u64 a_ptr — a device memory address (always 64-bit)

For pointer params, elem_type records the type of data pointed to (used by the code generator for load/store instruction types).

Variants

Scalar

A scalar value (e.g. .param .u32 n).

Fields

name: String

Parameter name.

ptx_type: PtxType

PTX type of the scalar value.

Pointer

A pointer to device memory (declared as .param .u64 name).

Fields

name: String

Parameter name.

elem_type: PtxType

Type of the data pointed to (for codegen, not the param declaration).

Implementations

impl PtxParam

pub fn scalar(name: &str, ptx_type: PtxType) -> Self

Create a scalar parameter.

pub fn pointer(name: &str, elem_type: PtxType) -> Self

Create a pointer parameter.

pub fn name(&self) -> &str

The parameter name.

pub fn ptx_decl(&self) -> String

PTX parameter declaration string (without trailing comma).

• Scalar: .param .u32 n
• Pointer: .param .u64 a_ptr (always 64-bit address)
