[−][src]Struct parquet::file::statistics::TypedStatistics
Typed implementation for Statistics.
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>,
null_count: u64,
is_min_max_deprecated: bool
) -> 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
) -> SelfCreates new typed statistics.
pub fn min(&self) -> &T::T[src]
pub fn min(&self) -> &T::TReturns 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::TReturns 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.

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S is the encoder/decoder state type, T is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
