}Expand description
Provides iterators over min and max values of a ColumnIndexMetaData
Required Associated Types§
Sourcetype Item
type Item
Can be one of bool, i32, i64, Int96, f32, f64, ByteArray,
or FixedLenByteArray
Required Methods§
Sourcefn min_values_iter(
colidx: &ColumnIndexMetaData,
) -> impl Iterator<Item = Option<Self::Item>>
fn min_values_iter( colidx: &ColumnIndexMetaData, ) -> impl Iterator<Item = Option<Self::Item>>
Return iterator over the min values for the index
Sourcefn max_values_iter(
colidx: &ColumnIndexMetaData,
) -> impl Iterator<Item = Option<Self::Item>>
fn max_values_iter( colidx: &ColumnIndexMetaData, ) -> impl Iterator<Item = Option<Self::Item>>
Return iterator over the max values for the index
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.
