Trait arrow::alloc::NativeType[−][src]

Expand description

A type that Rust’s custom allocator knows how to allocate and deallocate. This is implemented for all Arrow’s physical types whose in-memory representation matches Rust’s physical types. Consider this trait sealed.

Safety

Do not implement this trait.

Associated Types

`type Bytes: AsRef<[u8]>`[src]

Required methods

`fn is_valid(data_type: &DataType) -> bool`[src]

Whether a DataType is a valid type for this physical representation.

`fn to_le_bytes(&self) -> Self::Bytes`[src]

How this type represents itself as bytes in little endianess. This is used for IPC, where data is communicated with a specific endianess.
