Trait ViewType

pub trait ViewType:
    Sealed
    + 'static
    + PartialEq
    + AsRef<Self> {
    type Owned: Debug + Clone + Sync + Send + AsRef<Self>;

    const IS_UTF8: bool;
    const DATA_TYPE: ArrowDataType;

    // Required methods
    unsafe fn from_bytes_unchecked(slice: &[u8]) -> &Self;
    fn to_bytes(&self) -> &[u8] ;
    fn into_owned(&self) -> Self::Owned;
    fn dtype() -> &'static ArrowDataType;
}

Required Associated Constants

const IS_UTF8: bool

const DATA_TYPE: ArrowDataType

Required Associated Types

type Owned: Debug + Clone + Sync + Send + AsRef<Self>

Required Methods

unsafe fn from_bytes_unchecked(slice: &[u8]) -> &Self

Safety

The caller must ensure index < self.len().

fn to_bytes(&self) -> &[u8]

fn into_owned(&self) -> Self::Owned

fn dtype() -> &'static ArrowDataType

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
