Required Methods§

fn arr_from_iter_with_dtype<I>(dtype: ArrowDataType, iter: I) -> Self
where I: IntoIterator<Item = T>,

fn try_arr_from_iter_with_dtype<E, I>( dtype: ArrowDataType, iter: I, ) -> Result<Self, E>
where I: IntoIterator<Item = Result<T, E>>,

Provided Methods§

fn arr_from_iter_trusted_with_dtype<I>(dtype: ArrowDataType, iter: I) -> Self
where I: IntoIterator<Item = T>, <I as IntoIterator>::IntoIter: TrustedLen,

fn try_arr_from_iter_trusted_with_dtype<E, I>( dtype: ArrowDataType, iter: I, ) -> Result<Self, E>
where I: IntoIterator<Item = Result<T, E>>, <I as IntoIterator>::IntoIter: TrustedLen,

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.
