Struct DLDataType 

#[repr(C)]
pub struct DLDataType {
    pub code: u8,
    pub bits: u8,
    pub lanes: u16,
}

\brief The data type the tensor can hold. The data type is assumed to follow the native endian-ness. An explicit error message should be raised when attempting to export an array with non-native endianness

Examples

• float: type_code = 2, bits = 32, lanes = 1
• float4(vectorized 4 float): type_code = 2, bits = 32, lanes = 4
• int8: type_code = 0, bits = 8, lanes = 1
• std::complex: type_code = 5, bits = 64, lanes = 1
• bool: type_code = 6, bits = 8, lanes = 1 (as per common array library convention, the underlying storage size of bool is 8 bits)

Fields

code: u8

\brief Type code of base types. We keep it uint8_t instead of DLDataTypeCode for minimal memory footprint, but the value should be one of DLDataTypeCode enum values.

bits: u8

\brief Number of bits, common choices are 8, 16, 32.

lanes: u16

\brief Number of lanes in the type, used for vector types.

Implementations
