Struct deltalake::partitions::PartitionFilter

pub struct PartitionFilter<'a, T> {
    pub key: &'a str,
    pub value: PartitionValue<T>,
}

A Struct used for filtering a DeltaTable partition by key and value.

Fields

key: &'a str

The key of the PartitionFilter

value: PartitionValue<T>

The value of the PartitionFilter

Implementations

impl<'a> PartitionFilter<'a, &str>

Partition filters methods for filtering the DeltaTable partitions.

pub fn match_partition(&self, partition: &DeltaTablePartition<'a>) -> bool

Indicates if a DeltaTable partition matches with the partition filter by key and value.

pub fn match_partitions(&self, partitions: &[DeltaTablePartition<'a>]) -> bool

Indicates if one of the DeltaTable partition among the list matches with the partition filter.

Trait Implementations

impl<'a, T: Clone> Clone for PartitionFilter<'a, T>

fn clone(&self) -> PartitionFilter<'a, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for PartitionFilter<'a, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T: PartialEq> PartialEq<PartitionFilter<'a, T>> for PartitionFilter<'a, T>

fn eq(&self, other: &PartitionFilter<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &PartitionFilter<'a, T>) -> bool

This method tests for !=.

impl<'a, T: Debug> TryFrom<(&'a str, &'_ str, T)> for PartitionFilter<'a, T>

Create a PartitionFilter from a filter Tuple with the structure (key, operation, value).

fn try_from(filter: (&'a str, &str, T)) -> Result<Self, DeltaTableError>

Try to create a PartitionFilter from a Tuple of (key, operation, value). Returns a DeltaTableError in case of a malformed filter.

type Error = DeltaTableError

The type returned in the event of a conversion error.

impl<'a, T: Debug> TryFrom<(&'a str, &'_ str, Vec<T, Global>)> for PartitionFilter<'a, T>

Create a PartitionFilter from a filter Tuple with the structure (key, operation, list(value)).

fn try_from(filter: (&'a str, &str, Vec<T>)) -> Result<Self, DeltaTableError>

Try to create a PartitionFilter from a Tuple of (key, operation, list(value)). Returns a DeltaTableError in case of a malformed filter.

type Error = DeltaTableError

The type returned in the event of a conversion error.
