}

A selection of types to use in place of isize and usize.

Required Associated Types

type Isize: Copy + DropRaw + Send + Sync + Ord + Hash + Unpin

The type to use in place of isize.

type Usize: Copy + DropRaw + Send + Sync + Ord + Hash + Unpin

The type to use in place of usize.

type FromNativeError: Debug

An error occurred during type conversion from a native isize or usize.

type ToNativeError: Debug

An error occurred during type conversion to a native isize or usize.

Required Methods

fn from_native_isize(value: isize) -> Result<Self::Isize, Self::FromNativeError>

Returns the Isize corresponding to the given isize, or Err if the conversion fails.

fn to_native_isize(value: Self::Isize) -> Result<isize, Self::ToNativeError>

Returns the isize corresponding to the given Isize, or Err if the conversion fails.

fn from_native_usize(value: usize) -> Result<Self::Usize, Self::FromNativeError>

Returns the Usize corresponding to the given usize, or Err if the conversion fails.

fn to_native_usize(value: Self::Usize) -> Result<usize, Self::ToNativeError>

Returns the usize corresponding to the given Usize, or Err if the conversion fails.
