Methods
impl<T: DataType> TypedStatistics<T>
[src]
impl<T: DataType> TypedStatistics<T>
pub fn new(
min: Option<T::T>,
max: Option<T::T>,
distinct_count: Option<u64>,

) -> Self
[src]
pub fn new(
min: Option<T::T>,
max: Option<T::T>,
distinct_count: Option<u64>,
null_count: u64,
is_min_max_deprecated: bool
) -> Self
Creates new typed statistics.
pub fn min(&self) -> &T::T
[src]
pub fn min(&self) -> &T::T
Returns min value of the statistics.
Panics if min value is not set, e.g. all values are null
.
Use has_min_max_set
method to check that.
pub fn max(&self) -> &T::T
[src]
pub fn max(&self) -> &T::T
Returns max value of the statistics.
Panics if max value is not set, e.g. all values are null
.
Use has_min_max_set
method to check that.
pub fn min_bytes(&self) -> &[u8]
[src]
pub fn min_bytes(&self) -> &[u8]
Returns min value as bytes of the statistics.
Panics if min value is not set, use has_min_max_set
method to check
if values are set.
pub fn max_bytes(&self) -> &[u8]
[src]
pub fn max_bytes(&self) -> &[u8]
Returns max value as bytes of the statistics.
Panics if max value is not set, use has_min_max_set
method to check
if values are set.
